There used to be dumbphones for elder people with big buttons at retail stores not too long ago (at least at my place). Maybe these aren't advertised on the web.

Edit: don't know about US, though

On work we have also two rugged cellphones with a keypad. They have a color screen, but you can't really use the web, I guess .. I never tryed ..

I have seen those at Best Buy, the most popular is called the Jitterbug, which does come with a browser.
