I think he could be getting out at an opportune time. The rise of the Linux/SSD based mini notebook is at hand. Won't be noticed by many people for maybe a year or so, but they will sell themselves, and not just on price! A very few years down the line lugging the things people now lug around will be so uncool! Prediction: The MFF notebook will become almost as ubiquitous as the cell-phone is today.

I'd expect MS is already aware of the threat and will be doing ultra low-cost OEM deals on XP to - a very few dollars - a try to stem the threat. XP is slated to die next January anyway. MS would have to pay me to run Windows on a flash based device!
