If you're getting BBA the ISP you have usually isn't a problem, you just plug in and go.
Tho, if you're going 56k there's not too many ISPs that are easy to setup, from what I know AOL never worked on DC, probally the same for GC.
Lastly, there's the fact that there's no keyboard out yet, and from what I see it's going to be a few months untill the US gets one. You're only other option, rather than wait, is import one of those gay controller/keyboard things for Japan, and that's gonna cost you 60-80 depending on how quick you jump on it and where you get it.
I say it's totally worth it though. The on screen keyboard isn't that bad, I actually got pretty good on it. <img src="graemlins/eye.gif" border="0" alt="[Eye]" />
