The Apple iPad 2 Review
by Brian Klug, Anand Lal Shimpi & Vivek Gowri on March 19, 2011 8:01 PM ESTThe Web Browser
The iOS UI isn't the only area that doesn't get an update with the iPad 2, the core apps also remain untouched. Mobile Safari on the iPad 2 is effectively the same browser used on the iPhone 4, just on a larger screen.
Web page compatibility is generally pretty good on mobile Safari, with the obvious exception of any website that requires Flash. Apple continues its firm stance on not supporting Flash and hoping the rest of the world will convert to HTML5 or iOS apps. I'm personally not a huge fan of Flash, however I do believe the lack of Flash support is frustrating on the iPad. For most usage it's not a problem, but missing Flash is yet another reason why the iPad can't be an exclusive travel companion for me. There are still far too many niche sites out there that require the use of Flash. And if I'm in a hotel room with only iOS devices and no notebook, not having anything that can run Flash is a problem.
I ran two compliance tests on mobile Safari: Acid3 and the HTML5 Test. Acid3 is near perfect with the exception of an errant box in the lower right hand corner of the final test image:

In practice I have noticed more rendering errors and browser issues in Honeycomb than I have under iOS 4.3. There's one particularly nasty Honeycomb bug that I've encountered several times that prevents web pages from loading entirely until you kill the Browser process and restart it.
In iOS 4.3 Apple increased the performance of its JavaScript execution engine significantly. The result is pretty astounding. According to SunSpider the iPad 2 is now slightly faster than the Motorola Xoom, however BrowserMark puts the Xoom well ahead of the iPad 2. Google is extremely adept (and aggressive) at optimizing browser performance, this is one area where I'm not entirely sure how well Apple will be able to keep up in the long run.
JavaScript execution is only one aspect of the total performance equation however. Scrolling smoothness has been a staple of iOS and the iPad 2 does not disappoint here at all. Google made huge improvements in going to Honeycomb, but browsing in iOS is still smoother on the iPad 2.
Web page loading performance also proves to be quicker on the iPad 2, although given Google's advantages in BrowserMark it's clear that this won't be the case for all web pages.
Performance isn't everything when it comes to web browsing, and one area where Google maintains a significant advantage is in its support for tabbed browsing. Mobile Safari still requires that you tap once to bring up an array of browser windows and then once more to select the window you want to view. Apple limits you to a total of 9 browser windows.
The web browser in Honeycomb on the other hand implements tabs just like a desktop browser. Tabbed browsing has a profuse impact on usability, not unlike what we saw on the desktop (when was the last time you used a browser without support for tabs?). The fact that Apple still hasn't implemented tabbed browsing on the iPad is unacceptable.
Apple handles all memory management within mobile Safari for you, so if you happen to leave too many windows open and the iPad runs out of memory iOS will simply evict some of those web pages out of main memory. On the iPad 1 this was more of a pain as it only had 256MB of memory and a 1GHz Cortex A8 CPU, web pages were evicted more frequently and took longer to load when you went back to them. The iPad 2 doubles memory size to 512MB and loads web pages around 50% faster than the original iPad - making the experience much better overall.

Yes, as usual !PrinceGaz - Saturday, March 19, 2011 - link
Who buys worthless over-priced rubbish like the iPad, apart from hipsters/dickheads? I can understand the appeal of it to them, and I've nothing against dickheads who love them, but what purpose do they serve to the rest of us?!?It's incapable of being used for real work so basically useless except as a toy when out and about, but too large to be carried around in anything smaller than what a small laptop could be carried in, so what it can do when on the move may as well be done on a smartphone.

Cant beleive i'm saying this about an Apple product... but the iPad 2 isn't expensive for the hardware. Look at the Motorola Xoom which is lot more expensive for marginally better hardware, although the iPad 2 has better hardware in some areas. The thing is though Apple can sell the iPad 2 at little profit because they just make the money from app sales. So it's hard for other tablet makers to compete on price.I agree with everything else though.

The ipad2 is expensive, imagine if asus took their $250 10" netbook and removed the keyboard, replaced the hard drive with a sd card for memory, and ditched the intel mobo/cpu for a slower soc this thing would cost maybe $150.The only reason these devices have these prices is because that's how much people are willing to pay for them.
As for the xoom, motorola for some reason thinks they can charge a premium for it, they certainly are smoking some good shit. These phone manufacturers will fail with their expensive tablets.
Once asus and other netbook manufacturers start saturating the market with android tablets you'll start seeing cheaper solutions.

That is not true. FOB price for the 16GB XOOM clone(proper quality clone, not a knockoff) is about $330. Smaller components cost more.WaltFrench - Sunday, March 20, 2011 - link
“The only reason these devices have these prices is because that's how much people are willing to pay for them.”Showing off the fact that we've had Econ 101, are we?
Perhaps there's some object/service that operates differently that you'd care to mention.

Well, I for one think tablets are really great when you don't need a keyboard or a fast processor or a lot of storage. Which would be never. If the iPad sells way better than the Xoom, I'd say your theory about hipsters/dickheads being the only market group for tablets is confirmed.
