The 3G is almost compelling. However, lots of us already carry around a laptop with an expensive 3G account. I can only use one device at a time, and it's silly to me that I can't either tether to this with it's embedded 3G chip, or else use the same (capped) data plan for both. Since I can't, I'll stick with the laptop for everything. Of course that's the cell carrier's fault rather than Apple's, but it's still going to keep Apple from getting my money for one of these gadgets.
