Re: so....
I use my ipad for watching streamed video in the kitchen and then moving it around the house as I do other things (and light surfing).
A bigger screen and a louder speaker might well be attractive. Sure it's expensive but it will get used for several hours a day for the next 3+ years. I have a smaller Win 8 tablet but that is more difficult to use despite having easy access to a lot more content so not sure about a Surface.
