I actually like Gingerbread a lot and see it as an improvement. I'm not seeing all the issues others are. My battery life is IMPROVED (got 45 hours on extended battery last time, while it used to be 25-30 hours). No laggy keyboard at all - I use SwiftKey so not sure if that affects anything. Things also seem to run SMOOTHER and I generally like the new colors/affects (running LauncherPro).
There are some small issues I've had though (anybody know how to fix these?):
1.) Low resolutions photo when on a call - seriously? The picture quality of the person I'm on the phone with during the call is TERRIBLE. They were clear before GB, but now they're blurry. This is completely ridiculous and not sure why they'd change the compression of this. It's almost hard to see the person's face at all.
2.) Blinking LED for notification not always working - the LED usually works when an e-mail, text, etc. first comes in, but as I soon as I do ANYTHING (turn on screen, unlock screen, etc.) it turns off. Previously, the LED blink would continue with the color I designated until the notification was cleared from the status bar. I greatly preferred that way. And sometimes I don't get a blinking LED or notification at all....not sure why.
3.) Super bright hard buttons backlit - these are way too bright. No way to dim them; I'm not rooted so can't turn them completely off.
4.) Contacts not defaulting to last viewed (Favorites) - previously, on Froyo if I viewed my Favorites and then pressed back or closed out of my contacts, the next time I went to Contacts if would open favorites, which is basically always what I view. Now, it defaults to All contacts and there's no way to change it that I know of.
5.) Phone number in dialer - selecting a phone number in gmail SHOULD put all the digits in the dialer, but it simply takes me to the dialer with no numbers entered. I have to remember 10 digits? Brutal...
6.) Vlingo crash - probably a specific app issue, but when I open Handcent or some other apps sometimes I get a Vlingo has crashed error. Weird...I guess I should uninstall Vlingo; it's not even when I'm using it though, which is the oddest part.
7.) Seems like there's a longer lag to receive e-mails. Maybe this is just imagination on my end, but I'm not receiving e-mails immediately and before I pretty much always did...
Overall, I like it but if any of you have input on 1, 2, 4, and 5 above, it would be appreciated! Thanks!
