Great article from David Pogue at yahoo about the SP3
If all you need is a tablet, get a tablet; you’ll save money, weight, and thickness. If all you need is a laptop, get a laptop; you’ll save money, you’ll probably have more storage, and your machine will be more rigid and secure when it’s in your lap.
And, of course, if you prefer Apple’s unified, attractive universe of machines that work wirelessly together, well, then a Windows machine isn’t for you.
But if you own or carry around both a tablet and a laptop, then the Surface is calling out your name. There’s nothing like it.
