There is another machine Pentium 4 2.8Ghz HT machine with a GeForce 6200 and 2GB of RAM which also very powerful and has no problem with windows 7RC.The netbook which has these features: Atom 1.6Ghz processor with an on-board Intel-something video chip and 1.5GB of RAM has also no problem to run windows 7 RC.So there is also no problem on these three machines which are running windows vista.
