That's a nice wish, but there are several ways of getting "3G access", and they've all been discussed at length.

Right now, all NITs can get 3G access by pairing with a 3G phone over BT, and using DUN or PAN.

Other options include building a 3G radio into the tablet; this is bad because it ties the tablet to one particular technology, and likely to one or two frequency bands. Also, those without 3G service must pay for extra hardware they'll never use; while the price increase may be worth it for some, it'll probably stop some people from purchasing it.

The best option that I can see is to have some sort of slot, probably under the battery door, which would accommodate various 3G radios; this would cost substantially less than an integrated radio, would afford flexibility in network technology, and could be used for purposes other than a radio as well. The size tradeoff is still made, though, even for those not using a radio/storage/whatever card at all.

But BT's not bad at all, if a slot doesn't happen.
