First impressions..
I had a small freeze, music was playing while on home screen, wouldnt let me into anything, sleep / wake fixed it.
Typing is going to take me unlearn what ive already learned.
USB 1.0 syncing is taking awhile
TKIP wifi authentication worked.
Exchange server works, might be just cuz im on the domain's wifi, have to try off the domain.
XP / Outlook synced everything perfectly even while downloading and playing music and running Sophos update.
IT DOES flip both ways to landscape, not just counterclockwise like the ads.
Voicemail greeting setup volume was a little low, but I'm soft spoken.
Voicemail had me set a password but I assume its for remote retrieval only.
Can view txts and incoming calls while syncing as they arive.
Doesn't work w/o sim.
Youtube streamed while I was driving (

) crappy looking on edge but hey it worked.
Wifi hotspot also showed up in the middle of driving, ignored, you can turn this off.
Google maps work wonderfully over edge, given my experience with WM PPC 6700 on VZW, I was very impressed.
idk ill add some more later...
Update:
Built in call forwarding/waiting
show caller id
tty
exchange doesn't show up in the sync list, you have to add it manually (at least on outlook 03 on xp sp2)
