RIM is good at plenty of stuff: As any sore-thumbed business-type could tell you, they've got the whole email thing down. They can pump out software updates for a bunch of handsets at an outright impressive pace. With the BlackBerry Storm2, they've shown people that they can build the touchscreen device everyone thought they were building the first time around. Even with all these talents, one thing still drags them down, tarnishing an otherwise exceptional brand: their browser. After RIM snatched up the development company behind a WebKit-based browser back in August, it was pretty easy to deduce where things were going: there would be a new browser, and it'd be fueled by WebKit. For everyone out there not comfortable with deduction, however, we've now got good ol' fashion undeniable proof.
