Blackberry's bowser is inferior to the iPhone's and Android's. Even the most "pro" BB's out there admit to it:
"The new BlackBerry app platform leaves out much of the installed base; it only works on BlackBerry models introduced after the fall of 2006. RIM (RIMM) stumbled with its first touchscreen BlackBerry, the Storm. And its app store, and the apps themselves in many cases, are clumsier and less polished than the iPhonexxx8217;s. Most of all, the BlackBerry desperately needs a major user-interface overhaul. Email addicts who know lots of shortcuts love the UI, but itxxx8217;s very dated for a world where the device must do more than email. There are way too many clicks, steps and menus,
and the browser is still weak. RIM has just hired a new user interface guru who worked at Apple and Microsoft, so it apparently gets this problem." ~ Walt Mossberg
