While you won't be able to sense it at first, expect to feel a high frequency buzz from the direction of Redmond in the next few months. That's the Windows 7 and Office group fearing the rise of a new juggernaut on low-cost computing hardware, ChromeOS. ChromeOS may not be powerful, it may not play Far Cry and it may not run Microsoft Office but it's a game changer. The underpowered laptops that limped along under Vista, XP, or 7 will fly under a new ChromeOS regime and thin-and-light laptops will fall below the vaunted $199 mark as the so-called "Microsoft Tax" - basically the small cost manufacturers pay for OEM licenses - disappears.
