I'm not sure I like the idea of going completely to a touch screen. I've had iPhones go a little wonky at times and needed that physical button to clear things up.
How long before the government takes control of sites that hosts or links to information that the government just doesn't like or deems "unpatriotic"? What kind of oversight is involved before the government can just take down a site? I'm not pro-piracy or advocating it in any way, but I'm definitely all for due process.
