I use Swype and it seems to run just fine, in Rev you need to shift screens to access the other characters such as numbers (at least that is the way I know how to do it).
The Gingerbread update is getting into Rev and so many users are still finding things about it. As far as I can tell turning off automatic updates has been removed. I use my phone for PC Internet data, I have found the hotspot and the tether to be a bit touchy (connects but there is no data), if I restart the phone and computer the problems goes away.
Battery life does appear to have improved with GB, I have been able to turn off Juice defender which really made a difference for the previous version.
I live in a rural area, the 1X tower shows in the first second but the 3G tower can take over a minute to show up.
There appears to be a bug in GB, a case where the key lights won't come on, I have observed it to occur during a background service is running such as email or an update.
Hope this is what you are looking for, in summary I am happy with my REV, a lot of bag for the bucks.
