Playing golf with a friend who is an IT mgr for a local company.  He says tablets have pretty well replaced laptops for most all business people and his company is purchasing the new tablets installed with Windows 8.  I am not that up on the latest operating systems but he seemed to think it was pretty darn good.

Of course, if you are an Apple fan nothing will take the place of your I-Pad.

Just saying a lot of these tablets are now getting pretty good, both Apple and Windows
