The surface looks really promising as a tablet but I think they are trying to make it too much and posing it as a complete laptop replacement instead of a tablet. I love my tablet (Nexus 7) but there is no way I could replace my laptop, let alone by desktop with one!
At university I have seen a total of ONE, yes ONE surface being used - Even when Microsoft set up a stall begging people to try Windows 8 they had Sony Vaio laptops!
I feel it was a bit of a daft move building it on ARM CPUs, I mean, ARM is great but when it causes you to have to lose compatibility with existing apps then that's a huge turn-off and since the market share of Windows RT is so small there is almost no incentive for developers to build apps for it! Using some sort of ULV Intel chip would have been a much better move.
