More significantly, it's XP (which Microsoft users like), not Vista (utter crap, and so bloated there's no way to make it usable on a curent netbook). Microsoft were trying to kill XP by withdrawing it from the market, netbooks rather damaged that strategy.
And I suspect that most folks will prefer light weight over Vista capability, so MS won't have any future tech lifeline. A current Atom CPU is fast enough, running XP or Linux. Which will sell best, a netbook that runs Vista at a usable speed, or a Linux or XP netbook that's half the weight because it gets the same runtime from much smaller batteries? Mine's the six-hundred-gram one.
Now, why is it that no-one makes a netbook with a higher-resolution screen? Methinks Microsoft has a hand in that. Asus or someone, please launch a Linux-only high-res netbook, it'll force MS's hand the same way the original netbook did.
