no offense or anything, i wouldn't turn down an 8890 if someone offered me one, but i seriously can't imagine spending the amounts people do on cell phones.
dialing + dialing = bad
just don't do it, if not for your sake, then for mine and everyone else on the road
most new cell phones have voice activated dialing, flip it open and say a name and you're connected, you never have to take your eyes off the road through the entire call.
