Not surprising. My wife currently uses an iPad as her main device, but constantly has to switch back to the mac to do bigger word processing, etc. She really wants one device to rule it all.
We are looking at a Surface for her next machine. The way it seamlessly blends both multi-touch and pointer-based UI is really appealing to her - and me tbh.
I wish Apple would get off its high horse and recognize that maybe in Apple's purist sense they don't like mixing a touch OS with a pointer OS, but users want that. Enough with the Henry Ford analogies... these products have been on the market for a long time, so in this case, the customers DO know what they want. They are choosing what Microsoft is giving them rather than what Apple isn't.
