I've had 1.3 installed for a week and haven't noted any particular or unexpected slowdowns. I actually got the QuickGPS download notification today, been a while since I've had a ROM on long enough for that!

I haven't done a lot of "heavy" use on 1.3, though. Fairly light SMS, which I clean out after about 25-30 messages, check e-mail 10-15 times a day, post on Facebook occasionally, stuff like that.

One question I have ... do you guys use the Music tab? It seems to be a pretty flaky portion of SenseUI. For example, Showcase gets messed up for me if I've been playing music. If I pause music Showcase will never come up until I hit the Play button again and then it comes up out of nowhere. Freaky. It's a long shot to be sure, but it might be worth deleting the AudioManager_eng database, temporarily disabling the Music tab to see if that makes any difference.
