The model with 3G connectivity isn’t out yet. You can buy one with just wireless. If you choose to use 3G it is no contract, you can buy for a month at a time or a set amount of data.
As for wireless internet more and more places are giving it away for free, bookstores, restaurants, bars and so on.
I guess the device stands on its own merits then. Maybe I’m just jealous, but I don’t mind being wedded to a clunky old desktop to access the Internet. Funny how we’re having all of this freedom in communication even as other freedoms are eroding away. I can email somebody on the other side of the planet, but I won’t be able to buy an incandescent bulb.
