Hasn't this been discussed to death?
It's like this,
If you have 2 desktops, one has Win8 Pro and one has WinRT, but let's say for argument sake you could drop the ipad os on the desktop instead. Let's also say the prices fall in line with the tablets.
Which would you choose for your desktop?
The one that gives you limited ability? or the one that gives you full functionality?
I think the choice is obvious when you consider prices, and what you MAY want to do with it at any given time.
Yeah, you can throw in, what do you NEED, but let;s be realistic for a change.
If you want to go this route, that's fine,,, the largest majority of people don't need anything more than WebTV.
So, why even offer/suggest a desktop at all?
