If you're looking for some forums for the SK2, go to www.hiptop.com
Although, I do not prefer it, just because 90% of the crap on there is not english, it's all ebonics. I've never seen "dawg" and "repp" used more times in a sentence. Not to mention there's a fluke over there named "appletech" who worked for Danger who created the hiptop's, and everybody hates him. Too much drama for one to deal with.
That's why I like these forums, everyone has their heads screwed in, no one is trying to act cool, everyone is just here with a common love of the Blackberry. Not to mention all the great articles by Mark.
But if you're wife/fiance is looking for a toy that is mainly good for AIM/web/phone then I guess the Sidekick 2 is better for her. But when that thing breaks, which it will, seeings how the keyboard peels off so easy, just think "I could have gotten her a Blackberry" ....ROFL.
BTW, everything said about hiptop.com is purely opinionated, and with that comes with variety and preference. I PREFER these forums for the above reasons, however people WILL disagree with me, I realize that.
