This is what you call “hedging your bets”. This will be a great product which revolutionizes the market but in case it flops we won’t totally shoot everyone in the foot. Nice. Way to believe Microsoft, way to believe.
In truth though, I am running Server 2008 64 bit on my laptop with the desktop experience on and it runs fantastic WAY better then XP ever did. If Microsoft can just do the same thing with Windows 7 they may actually have a success here.
