Okay so here is what I have observed,
1. noticeably improved battery life. in 8 hours, I have only used 20 to 30% of the battery. pre-update 20 to 30% of the battery was gone in 2 - 3 hours.
2. phone is much more responsive. I didn't have the grounding issue, but the responsiveness improvements are noticeable
3. peep has been a little buggy. from saying no tweets to just closing on me. i did a reset (which is why i gave a range on the battery) and things have improved.
4. wifi signal has improved somewhat i suppose. Where as before the update i got no bars in my bathroom, I now get a bar 60% of the time I am in there.
5. long press on the keyboard works
6. Qik is always running in the "Running Services". This is new and interesting.
I updated this morning around 10:30 am while on the ****ter at work. got a little nervous because it took so long, but I stuck with it and everything came out okay. Lets hope the froyo update goes smoother. Maybe sprint/htc should provide us with more instructions like "this is going to take a long time to install, so dont turn your phone off. Do not try to reinstall this update after you have already installed it."
