You don't need no stinking "online ordering"- they were selling and have inventory that is NOT all online. Go and get the latest, greatest at your local Apple store...
Do they have just the three "unmodified" models (128/256/512), or can you also get some of the BTO-like options? I ordered 3.1/1T/16GB, and I want those specs, but if I can go buy that in a store today rather than waiting a week, I'd probably do it.
