Too be honest I've yet to purchase Skyrim. I first started playing Oblivion on the ol' Xbox and a year or 2 later I played it on pc and my god how the pc version is vastly superior thanks to all the mods.
My pc can't run Skyrim, I thought about buying it for Xbox, but I'm afraid that jealous feeling for the PC version will ruin my experience. Also, I don't want to upgrade my pc before the Next Gen comes out, because some one told me we'll have new hardware that will use different architecture so it's not really that usefull to upgrade now. (And by upgrade I mean buying a new pc that will last me for a while, my pc's 8 years old now so, but it's getting old

.
If I do get around buying it for Xbox, I'll probably wait for a GOTY edition.
