10 reasons why a netbook is better than an iPad
When Steve Jobs said back in January that the iPad is "way better than a laptop, way better than a smartphone" – because it was "so much more intimate than a laptop and so much more capable than a smartphone" – people were sceptical at best. Now, more than a week after its launch, their doubts have not yet been completely exorcised.
While it may be obvious that an iPad could never compare with the raw general computing power most laptops offer, placing it alongside the laptop’s more specialised cousin, the netbook, seems more realistic. We take this opportunity to see how they compare in terms of their ease-of-use and functionalities.
Let’s get down to it...what makes a netbook better than an iPad?
- Multitasking – Though the latest announcements about the iPhone OS 4.0 explicitly state that multitasking will be available on the iPad by Fall 2010, it remains to be seen if the form in which it will arrive will compare to the known efficacy of netbooks, which with quite a bit more RAM will definitely have an easier time keeping up with the most hardened multitasking user.
- Web camera – Apple Inc. might really have goofed up on this one. A very common use for a MID, laptop, smartphone, modern tablet is to allow you to stay connected with your friends, family, and colleagues from across the world.
- A complete browsing experience - No matter how much Apple wants you to believe that Flash is not required and how many times Steve Jobs might say the iPad offers the "best browsing experience you’ve ever had", much of the world - innumerable small webpages and large webpages - still work on Flash. Though changes are on their way and many sites are offering iPad compatible versions, you can expect it to take a while before even a quarter of all the sites in the world will do so. The smaller sites might possibly never convert, and one should not underestimate the value of those sites.
- USB-connectivity – The holy grail of inter-device connectivity, USB support will allow you to connect a variety of devices to a netbook, from game controllers to external storage devices, USB modems to printers, webcams to digital/handycams, even those devices (like some PMPs) that require to be charged through USB.
- Storage – The iPad will offer a maximum of 64GB storage, and does not provide built-in support for SD (SDHC) cards. It does provide a SD card-reader dongle however, but, in typical Apple control-freak fashion, it will only allow you to import images and videos on to your iPad. Compare these limitations to most netbooks, which offer 320GB HDD space, external flash drive support, and built-in SD card support.
- OS of choice – Not only will you not be limited to what applications are available in the Apple App Store, you can install a variety of OSes, from Ubuntu to Windows 7 Starter; and depending on the sufficiency of your netbook specifications, even full-scale versions
- A built-in keyboard – The iPad’s onscreen keyboard, reviewed by many to be fast and responsive, still takes up more than its fare share of real-estate on the screen, especially in landscape mode. The iPad, weighing in at 2.4 pounds, is also too heavy to allow holding it with one hand while typing with the other to be quite unfeasible. Though the iPad offers an external keyboard that serves just as well, it has to be docked, and the entire setup cannot be dangled on your lap like a netbook can.
- HD – The iPad will play only 720p HD, while quite a few netbooks offer 1080p HD video.
- RAM – With the iPad bearing just 256MB of RAM, you can expect the speed and scope of applications developed for it to be limited, though they will undoubtedly be speed-optimized. Compare that to netbooks, many of which offer 2GB RAM, with upgrade options.
- Replaceable battery – One day, your netbook battery will give up, as will an iPad’s battery. But, it is far simpler to buy a new netbook battery and replace its old one than on an iPad, for which you will have to pay a $100 and surrender your old tablet. It might also take weeks for Apple to deliver the new device, depending on their service coverage in the area you live in.
Also to be noted, is the fact that if you wanted a touchscreen device, but not with the limitations of an iPad, you do have the option of getting a touchscreen netbook. The combination of both touch-screen input along with keyboard/mouse give those netbooks that do offer it an added advantage.
To be truly fair, we look at where an iPad might pull up ahead of a netbook.
Let us look at some aspects of mobile computing where the iPad might have an edge over netbooks:
- 10 hour battery life – Yes, it really does have a battery life this long, with several different tests confirming it, while actually playing video for a substantial portion of the time. However, its battery is not detachable or replaceable; though just like a netbook or laptop it will give up one day. You will need to pay $100 to get the battery replaced (technically, you will get a new battery in a new iPad, with your old tablet having to be returned – causing all sorts of data backup headaches)
- Accerelometer/GPS/magenetometer – Though these features may not really be an advantage, they will allow applications to offer some very unique functionalities, such as UI auto-rotate, turn-by-turn navigation, location-aware search and networking, and much more.
- 3G – Available in the higher-end iPads, this will give users great data/voice connectivity and transfer speeds, only useful if you have 3G networks in your area.
- Touch-screen – Though not really an advantage, those looking for it will find to be responsive and a delight to use on the iPad. However, while some may consider a touchscreen to be an intuitive input method, the ease and tactile comfort provided by a keyboard (yes, even a netbook’s) and the accuracy of a mouse cannot be underestimated. Some functions however, like drawing or writing directly by hand. Some netbooks however, come with touch-screens.
- Boot-up time – The iPad, with a stunning 30 day sleep/standby time, will switch on almost instantaneously whenever you want it to. All netbooks have to boot-up however. But to be fair, quite a few netbooks offer a feature that is variously called “Always-ON”, “Express Gate”, and many other things by different manufacturers, which allows you to access your mail, browser, and some of your media before and while your computer boots-up.
So, is the iPad really for you? Do you feel that it is more useful? Do let us know what you think...

Namechk
Namechk scans more than 140 sites to find people open usernames.
(Credit: Screenshot by Josh Lowensohn / CNET)Namechk launched this time last year and lets you scout out open usernames across a handful of sites. This is useful for companies that want to establish a new brand on places like Facebook and Twitter without having to do all the legwork. For basic users it can also be a simple way to discover new sites where you might be able to get away with using the same log-in.
When we first covered it, it handled 84 different sites. It's since gone on to support 145.

BSNL 24 megabits ultrafast broadband to India | Ub News
BSNL now offers 24 megabits (Mbps) “ultrafast” broadband to India. The launch of BSNL 24Mb service is a historic moment as it is the fastest internet service in India till date.
The internet is required by everyone even it is more necessary than a shower these days. People now regard fast and reliable internet access as more important than hot showers. Young generation can live without taking bath but they care if they can’t play video games and can’t access chat with friends online.
The new ultrafast broadband will come through Digital Subscriber Loop (VDSL) Technology.
To avail this service, subscribers will have to pay Rs. 4,999 a month for speeds up to 16 Mbps and Rs 9,999 a month for speeds of up to 24 Mbps.
There is still one miss in the service that 24 megabits broadband service will be available for customers located at a distance of up to 500 metres from the BSNL exchange, 16 Mbps broadband is available to only those residing up to about 1 km away.

Power plant in a Box
Supporters are claiming K.R.Sridhar’s ''Bloom box,'' scheduled for a big-splash unveiling in Silivon Valley on Wednesday, could be the Holy Grail of the world’s energy quest; and even skeptics agree that it is a unique ''power-plant-in-a-box.'' What acres of power grid can generate, Sridhar’s Bloom Box can crank out in a fraction of the footprint -- in a squeaky clean manner too.
It is already being done -- on the campuses of Google and eBay among others. FedEx, Wal-Mart and Staples are among a score of Fortune 100 companies that have signed up as clients. Former Secretary of State Colin Powell, among those who endorse the technology, is on the Board of Directors of Sridhar’s Bloom Energy, an eight-year old stealth start-up that raised more than $ 400 million from Silicon Valley’s venture capitalists at a time the region’s economy was in a tail-spin.
At its heart, Sridhar’s Bloom Box claims to be a game-changing fuel cell device that consists of a stack of ceramic disks coated with secret green and black "inks." The disks are separated by cheap metal plates. Stacking the ceramic disks into a bread loaf-sized unit, says Sridhar, can produce one kilowatt of electricity, enough to power an American home – or four Indian homes.
The unit can be scaled up, installed anywhere, and be connected to an electrical grid just like you would connect your PC to the Internet. Hydrocarbons such as natural gas or biofuel (stored separately) are pumped into the Bloom Box to produce clean, scaled-up, and reliable electricity. The company says the unit does not vibrate, emits no sound, and has no smell, although Sridhar admits to some initial, but minor, glitches at some installations.
A hoax it is not, although some are suggesting there is a lot of hype around the launch -- somewhat like with that of the Segway transporter that was much bally-hooed but did not live up to its billing. As with Segway, the big catch right now is cost. Large-sized Bloom Boxes of the kind installed at some Silicon Valley campuses costs around $ 700,000 to $ 800,000. Sridhar estimates that a Bloom Box for the residential market could be out within a decade for as little as $3,000 to produce electricity 24/7/365. "In five to ten years, we would like to be in every home," Sridhar told CBS' "60 Minutes" on Sunday night.
But Silicon Valley, whose major venture capitalist Kleiner Perkins’ bankrolled Bloom Energy, is endorsing the technology. EBay said it has already saved $100,000 in electricity costs since its 5 boxes were installed nine months ago. It even claims that the Bloom boxes generate more power than the 3,000 solar panels at its headquarters. Google has a 400 kilowatt installation from Bloom at its Mountain View headquarters. California’s governor Arnold Schwarzenegger will be at the launch, which is to take place on the eBay campus.
The man at the center of all the excitement is Dr K.R. Sridhar, 49, who, prior to founding Bloom Energy, was a professor of Aerospace and Mechanical Engineering as well as Director of the Space Technologies Laboratory (STL) at the University of Arizona. He is also, literally, a rocket scientist, having served as an advisor to NASA in the areas of nanotechnology and planetary missions. Sridhar initially developed the idea behind the Bloom Box while working with NASA, as a means of producing oxygen for astronauts landing on Mars.
Dr. Sridhar received his Bachelors Degree in Mechanical Engineering from the University of Madras, India, and moved to in the 1980s to the U.S, where he earned an M.S. in Nuclear Engineering and Ph.D. in Mechanical Engineering from the University of Illinois, Urbana-Champaign, home to such start ups as Netscape. On Sunday, CBS’ 60 Minutes homed in on Sridhar’s breakthrough technology, bringing huge attention to Bloom Energy’s bare-bones website that ran a cryptic visual saying ''Be the Solution'' -- and a clock counting down to Wednesday’s launch.
