We'll get something in the mail about the specs, but I don't think they care about the OS as long as the compy you gets meet the specs. If you have a computer and don't really want a new one, you might be able to get away with keeping your machine so long as it's up to snuff. But we'll have to wait til they send us something. I don't think the specs will be anything outlandish, either, so you can pretty much start shopping if you want. I'm looking into tablet pcs, so I can take notes right on the many, many powerpoints we'll have to sit through.
