I don't know that I would directly compare Windows 7 and Windows 8 as far as demand. After Vista, people were ecstatic over Windows 7 and bought it in droves even with the higher price. A lot of people and especially businesses had skipped Vista completely and were thus upgrading from XP. It wasn't just huge at launch, it built momentum as people began to trust Microsoft a bit more based on the positive press about Windows 7. Vista had angered a lot of people. I think with Windows 8, we're seeing a lot of upgrades based on how cheap it is, as Windows 7 satisfaction was pretty solid. I think it's less excitement and more, "sure, why not." The exception would be the true-blue Microsoft fan who buys everything Microsoft makes and wants all their stuff connected.
I don't know about anyone else, but personally, I don't want everything I own to be connected under one account. I don't like that at all, especially when some devices are mobile. If you think Windows LIVE accounts (a term Microsoft no longer uses, I know) were big targets before, it's going to get even worse.
Even without that, I refuse to buy things because they match with other things I own. I'd much rather select the best products based on their own merits.
