IPad 2 Browser

Apple claims big gains in the speed and performance of the new iOS browser thanks to the introduction of the Nitro JavaScript engine to the underlying Mobile Safari software. In our testing, we scored a fairly healthy Sunspider number of 2173.1ms (while Google's V8 returned a score of 338). Nothing to freak out about in comparison to the laptop numbers below -- but compare those digits to the iPhone 4 and original iPad running 4.2. Of course, the Motorola Xoom is neck and neck with the iPad 2 in terms of browser performance, which shows that speed is most certainly not Apple's domain alone.
