Hey, if it works, yes, the problem with a flash drive, is if you plug it into a bad USB slot, it could fry it.
what notebook that can support win 7 does not have a dvd drive? I'm sure there's one out there but they would be very rare, unless windows wants to do a lite mobile version which would be kinda cool... there's an idea for you microsoft! make me something for my laptop, and you could make the flash drive a bit smaller in capacity, cut out all the fat and just make everything downloadable...Uh people with netbooks who like want windows 7 and either have xp,vista or even window 7 starter.
And the memory stick would only be 3gb. Because isent the iso for 32-bit only 2.35gb or so.
But with a DVD, simply dropping it on the floor could scratch it up beyond use. I think selling it in flash drives is a good idea (that's all I use to install builds of Win7 now anyway) except i think MS would lose a lot of money because they're giving you a free flash drive. You could buy Win7 on the flash drive, then copy the contents of the drive somewhere else, format it, and there you have it: a ~4GB flash drive and Windows 7 for the price of just Windows 7.
