We so fondly remember Palm's Roger McNamee stating the Pre would be a million times faster on the web than the iPhone (now retracted), and even our sister-site PreCentral.net jumped on that band wagon, saying the Pre looked to be 4x faster than the iPhone.
Of course, we mentioned that on Sprint, lacking simultaneous voice and data, even a million times zero is still zero. Less flippantly, however, when Safari 4 Beta shipped for the desktop with its new ultra-fast Nitro (formerly SquirrelFish) rendering engine, we figured it would only be a matter of time before that scaled down to the iPhone's version of Safari (based on the same WebKit foundations as desktop Safari, as is the Palm Pre browser and Android Chrome Lite).
From what we've seen of 3.0, it seems that way to us as well. Along with HTML5, CSS, 2D and 3D animation, anti-phishing, AutoFill, etc., it will be interesting to see what Apple and the WebKit team can pull of by the time iPhone 3.0 launches this summer...
