Stay with W7 for as long as possible
It's incredible that MS keep on shooting themselves in the foot so frequently. This time they have shot themselves in both feet. Win 8 on desktops in business will be a disaster. Businesses will eventually jump across to OSX where they can see a familiar GUI style and kept apart from IOS, or alternatively in the current financial climate it will make sense just to keep on sweating assets longer and use a familiar GUI with Linux Mint for example. The learning curve for a user on a good linux OS is going to be LESS than Win 8 and once up to speed with linux they will not be still complaining about tiles and their system getting hosed by a virus, unlike Win8. MS are only doing this so that when the masses get a new PC with Win 8 on they hope they will immediately identify with the same interface when those consumers buy a phone or tablet. This is the worst kind of homogenisation imaginable and it will fail.
