Just last week I have set up a new Dell Netbook with Windows 7 for a friend -it only had 1Gb, yet runs fine (for that amount of RAM!) - I don't have a Netbook myself, I just find them too slow, and don't need the ultra portability, my laptop is old, but still a lot faster than one! Anyway, having run it with XP as it came, I can say there is barely any noticeable speed difference at all with W7, one way or the other, so if you want 7 put it on! (Watch what you do when disabling services, it behaves a bit different to Vista, especially if you want to keep the Media Center functionality!) I am not using W7 myself yet, as it is a bit early for me to go the whole hog with a new OS, but I don't think it will be very long, as I have tried it out on other machines and it is certainly very good. For those beings with educational staus, here seems to be cheapest at the moment: http://students.pugh.co.uk/index.php?nID=productDetail&manu=50&prodID=2830 at £32.66 for the Professional version!
