Has anyone used both the iPhone (3GS) and the MyTouch 3G extensively? Can you give me a comparison? I have used an iPhone/iPod touch a lot and I am wondering if I will be disappointed at all with the MyTouch. How does the web browsing experience compare? I use only GNU/Linux on my computer, so I am looking forward to that aspect of the phone if I get it. But will any UI or feature quirks make me wish I had gotten an iPhone?
