@evildictaitor: Or just as silly as a business user with Office, a few LOBs apps -- some with local data storage, and a whopping OST thinking they can use Surface instead of a laptop. Some sales guys I know will clog even that 128GB model up in no time. IMO, the 64GB doesn't have a prayer.
So that leads back to the questions of "What is Windows 8"? "What is Surface?" I thought Microsoft's big stick in this game was that Windows 8 (and as an example Surface Pro) could provide both your tablet experience and your desktop experience. I'd even be willing to limit the latter to "your laptop experience". In the end it's none of the above.
