My machine is a year-old, uncustomized stock tablet PC that has Vista on it. And I was a software engineer at the evil empire for 15 years, so I'm cocky.
Since Nova's aiming to buy Dells, I know we're not required to get a Mac.
Since it's REALLY hard to get a new machine without Vista on it, particularly in a group package deal, I assume Vista's going to be okay.
If we all have to be on XP, I can figure that out. Vista lets you run a virtual XP session (here you probably fall asleep).
If there's a piece of hardware required, which is a fringe case, it will be a peripheral (like USB etc.) or the Dell deal wouldn't work. Making Dell put a piece of hardware into a laptop means a lot of extra cost and overhead, times 250 students, and then they'd require EVERYBODY to have the custom machine.
Thinking it through I'm about 85% confident. This will be like having to run "Nova for Windows version 1" and there are 3 scary terms in that product name.
