I'm sure Nokia N97 fans and iPhone 3G S fans are having some little "my phone is better than yours" squabble for quite some time now. Here's a video from The Nokia Blog showing which one is more superior in terms of web browsing, so no more fighting necessary. ;)
Based on the video, I noticed the N97 screen flickered, so I suppose the refresh rate was lower. There's no multi-touch for N97 - which we all know. Web page scrolling/zooming were a little sluggish and loading of web pages was also slightly slower.
