Great news! I've just got out of hospital after a major operation on my left knee, so this was a pleasant surprise...
I'll be upgrading as soon as, even though I've not even got the hang of X1 fully. I probably won't even benefit from any early adopter promotion because I've already filled my boots with all the Rapture + PC goodies in the past couple of months.
That's not going to put me off from adopting early though...
