The problem of iTunes not recognizing the newly configured iPad when it is plugged in for the second time is apparently a feature, not a bug. iTunes does in fact recognize the iPad, but the dialog box is misleading. Seems nutty to me, but it's also a one-time thing, so I'll get over it. Minor Apple fail, resolved.
AT&T fail continues in full cry. I will be pursuing it as time and energy permit.
Two more points, for now. This thing really is very cool, but man do I wish it had tabbed browsing. The iPhone's browser model is tolerable if disappointing on a phone, but for the iPad to really live up to its promise for me, more normal web browser behavior is critical.
Also, I owe a post expressing my depth of gratitude to the shadowy consortium of friends, fans and a few kind strangers who chipped in to buy me this thing. You guys are awesome beyond words.
And yes, I'm making this post from the iPad.
