I’m in line, as I write this, waiting to buy an iPhone. Yesterday I bought a 3G ExpressCard for my MBP, and discovered that it doesn't work very well. I gave it to my buddy Mike to use, and he’s sharing the internet connection over WiFi (it seems to work much better for him).
A while ago one of the store employees came out (this was after a FedEx delivery at about 1300) and said, “I can’t reveal specific inventory levels, but all of you,” as he gestured to the whole line, "will be getting an iPhone."
It’s now 1428. Less than four hours to go…
Update (1438): I’ve just plugged the MBP into my buddy’s Vector Power Supply. Among other things, it includes a 200 W power inverter.
