Surface Pro is another device for it's purpose
Personally, I don't see the point of an ipad/tablet. Basically, large smart phones that can't make calls. Why have a macair, ipad, and a iphone....putting apple aside.
My wife an I originally bought new lighter laptops, but found they did not quite fit the need. Tablet/ipad really didn't fit the need (wife has an ipad from work, that mostly collects dust). the Surface pro 2 looked like the ticket, which we bought.
Keep in mind, this is a different device, treat it as such. It fills a nitch I think the author discussed well, if not in too much detail.
True, it does lack the clamshell design, but then if Applie never made the iphone, how would we know we liked that new device?
She uses the suface pro 2 in many places, but loves it most of all at school (masters), or in the car (rider). Sits great in the lap, and in class, the surface sits on the desk, while she uses the remote keyboard on her lap. This does not take up much room on the desk, and allows her to be more productive. We are looking forward to the SP3.
The question really is price. it's a bit high, but so are apple products - Apple has a known 30+% markup on all their products. If people can afford it, and like it, go for it. i highly recommend the SP line, but it comes with some understanding that it is not a laptop nor a tablet. Significantly better in most cases, lacking in others if you want it to be one of the others. I think the MS marketing had the right idea, but executed it incorrectly.
