Tethering is what it's all about with the internet tablet. Having a usable tablet anywhere makes it a part of you! I use T-mobile in the US, and have no problem, other than the fact that the n810 doesn't like to keep a constant connection with the N95-4.

If true, the next tablet may have HSDPA. I think this is a great option if you want to pay for another line, but tethering should also be there as well.
