I'm under the impression that you can only purchase 1 per person (or per transaction?). So group and bulk buys are out of the question. 10,000 units might last a bit longer than 1-2 hours, but only time will tell.
Just wait a couple of months and you'll probably be able to pick one up on the cheap from people looking to offload something sitting around. These are a lot less powerful and have a lot fewer connectivity options, unless you want to do some soldering, then people are believing. It also doesn't help that the main selling point (accelerated graphics) will be shipping as a binary blob.
