you should watch some of the video reviews,

google backs up your contacts to your gmail account.
the phone most likely will let you connect thru the usb. it's like a standard thing now.
you'll have to pay an additional $30/mo to tether unless you root it and go about it in a devious manner, :-p
most reviewers have mentioned the sound quality is great
android has the largest percentage of free apps of any marketplace
there is picture dialing, watch the video review, i suggest the mobile burn review.
android is much better than winmo (i own the tp2)
