Personally, I'm rooted and have Smoked Glass Blue installed, and I'm NEVER going to the official 2.1 update unless i absolutely have to.
I have/see all the new stuff with 2.1 now. Phone is overclocked and runs 100%. No issues. Super fast. NO lag.
Thing just *ROCKS* now. I mean, its easily the nicest phone I've ever seen, makes the iPhone look like CRAP. I thought they were neck and neck when I wasn't rooted, now that I have 2.1 rooted and all these other rooted things installed, its not even close.
Personally, I have GDE installed. Its not exactly 2.1 friendly. I don't get the nice animation with the app drawer, but thats fine.
I honestly couldnt' understand how people were saying earlier "I'm just staying rooted, no need to get 2.1", I mean, aren't they all just "playing" with their phones until 2.1 comes out?
NOW I understand. They have 2.1, all the options (except flash I think), and they can do even MORE than regular 2.1 users because they have root so things can be customizable. Also, the blue smoked rom has blue highlights everywhere, which is perfect with the blue themes I usually prefer.
