I love my droid 2 global but I really think that gingerbread is going to be much better on it than froyo is. So I'm hoping that verizon/motorola will soon come out with an update (though I'm sure the droid x and incredibe will get updates before d2g and its not going to help that verizon is going to be preoccupied with the release of the Iphone and the new 4g phones). Also I've decided that as soon as I'm due an upgrade I'm changing to htc. Sorry moto you make great hardwear but I think I will like sense way better than this semi-motoblur thing.
From my experiences with Gingerbread, it's honestly not that big of a jump from Froyo, mostly some minor UI changes that may even be overriden by MOTOBlur. I believe there are some speed and battery life adjustments made as well, but probably nothing really noticeable.
Honestly Gingerbread is the smallest jump over a previous android version out there, and not really worth the fervor. Just be glad you have Froyo, those of us with Galaxy S phones are still (officially, at least) on Eclair!
