I wasn't impressed until I saw the price and the thought of paying $30/month for 3G without a contract.  I can take this on a trip, use maps for navigating my route, get on the road and hand it back to the kids to watch a movie on iTunes on a reasonably sized screen.  I can think of a bunch of ways I could use this.  I also really don't like talking on the phone, so I don't really want voice anyway. :-)
