Lets face it, mature Linux 64bit OSs continue to be hampered by the lack of drivers drivers so Windows has a lllooonnnggg way to go. If M$/AMD want to reach the tipping point faster, instead of giving away systems to bloggers, why not give away a 64bit version of Vista with every 32bit version sold (its not like M$ are going to _sell_ many 64bit Vistas)? It won't fix things overnight but I reckon that, by the time Vista's replcement comes along, the tipping point may very well be there. Personally, I'd buy a 64bit Vista tomorrow if it was effective.
