Windows 7 on thumb drives for netbooks?

So apparently, Microsoft is considering several options to make it easier to sell Windows 7, especially to netbook owners. In the light of the Vista fiasco, MS has promised that Windows 7 will be a netbook-friendly OS, the one that will probably give Linux the death blow (sadly) in the mini-laptop segment.

And USB thumb drives are being considered. I say go, this is a nifty idea.

But one-time use thumb drives would be a pretty weird thing to see, right?
