Arnie87 writes "One Microsoft Way has an interesting article suggesting that the reason Microsoft is focusing so much on speed with Windows 7 is the whopping sales of netbooks. The article concludes by saying: 'If you plan on adopting Windows 7, you have the netbook to be thankful for, because Vista's successor would be a very different beast if Microsoft had less motivation to pursue performance.'"
