LOL. Careful, the jump from a Pearl to a G2 might put you in the hospital overnight It's the fastest, and smoothest Android phone I've ever used, and the stock Android experience it runs is hard to come by anymore.
Not sure when you're planning on switching, and I'm not usually the guy who says to wait for the "next big phone", but T-Mobile has a damn nice one coming up in the MyTouch 4G soon, too.
I'm an BlackBerry convert myself. You'll find a lot of us here
The Og looks like an awesome device. Right now im on a Motorola Charm. Even though there's not alot to it I really love it. I had a Mytouch slide and gave it to my daughter after she begged me for it. I didn't think I would like the charm as much as I do.
