Sorry if this is a repeated thread, but this is what i've noticed... chime in and let me know if you've noticed the same or if there's things i've missed!
The Good
-----------------------
Overall stock app appearances have improved (except for messenger app--in my opinion)
Much improved market with AUTO UPDATE and UPDATE ALL!! yay!
plus it has a fun little widget!
Install Apps to SD Card!
USB Tethering
Flash capable (download i used in case you can't find it in market)
App launcher lower bar with phone and browser shortcuts
5 screens
270 app rotate
better camera
Seems that calendar and corporate calendar have been merged... Note: if you have problems with Exchange, clear your cache and reboot.
You have to option to end a call with the power button... I like this since i used to have to sit around and wait a little while before the proximity sensor kicked in and realized the phone was away from my face.
Combines similar calls within Call log
Better "Manage Applications"
New security locking options
The "meh"
-----------------------
Auto brightness in power control widget (its a nice feature, but seems to kill battery at least for me)
Noticed it changed the color of the line next to my emails (the color code so you can tell what email is from what account)
Vibrate function seems to have a problem... To fix this go into your sound settings, change the vibrate setting, then change it back... seems to reset the hiccup and make it work.
Improved? User interface for USB Mounting (necessary?)
hold home = 8 most recent apps
The Bad
-----------------------
Messenger app now has white background instead of the black background and has the user's facebook image (or a standard android image) next to each message (wish you could turn this off and set the background back to the black...)
Seems that it takes greater force to change between 5 home screens... I used to be able to lightly stroke the screen, now i have to get a little forceful... yeah, that sounds a tad funny
