I think this would be nice. Apps that would allow you some sort of ESO interface/interaction could be neat, but I doubt you'll see it played on a tablet.
Unless some like a smartphone app that let talk with the guild. RIFT has a mobile app let players do that. I never used that myself. Also, to add layer to help to protect one's account password type app idea.
That's probably because Skyrim is NOT an MMO...
There are quite a few tablets that run Windows 8.
I take it the surface is using the built in hd xxxx from the I series not a dedicated gpu so even if you could run it! it would be on the lowest settings to avoid a slide show and for 720£ I'd build a pc that runs it max or buy the Xbox One and ps4 lol
There are a number of tablets that run the full version. http://en.wikipedia.org/wiki/List_of_Windows_8_and_RT_tablets
