It's disappointing :( I work in education and would like to try this thing out for a variety of projects, but the delays in getting them to market mean I probably won't get one. There are alternatives, not least (for the very interesting original article) just setting up a Linux box and using Hercules, etc, on that. It's a real shame that supply problems risk putting a damper on the huge public interest and enthusiasm for the Raspberry Pi.
Its disappointing in the short term, but look at the big picture. All this extra interest and purchases from the private sector if handled correctly will let them buy in bigger bulks, twist more arms in manufacturing, and find and fix more bugs. In the long run getting this boards out to a wider audience will give you a more stable, feature-rich and cheaper product.
I hope that will be the case. My ultimate motivation is to get students interested in programming and all the other things (control tech, etc) a cheap expendable PC can facilitate. I could easily get 20 of these if they were available but getting one is tricky enough at the moment.
