The iPhone does have the best "web browsing" experience. I hate the virtual keyboard though. I really want some kind of hybrid. iPhone screen and web browser with a blackberry-like keyboard.

Two things your wife can try with her blackberry though:

1) When viewing a web page, press the blackberry key ( just to the left of the scroll wheel ), and select "column mode". If that works better, there's a way to make it the default.

2) Another idea is to try a different web browser. Opera Mini can be better than the built in browser: Opera Mini - Download: BlackBerry. There's also a new browser from bitstream.com called Bolt: http://www.boltbrowser.com/download.html
