I bought a copy from Staples when they had the $40 sale price last week and I also got a key for the Media Center download. I’ve installed Win 8 as an upgrade on a secondary PC that had Win 7 on it, but I probably won’t be installing Media Center on that particular PC. At $40 it’s not going to break the bank just to check it out. It’s going to take some time getting used to the new interface, but it definitely looks interesting.
Considering the lack of support for Media Center and lack of Win 8 drivers, I see no compelling reason to “upgrade” my HTPC with this software. Since MS has done nothing to update Media Center it makes absolutely no sense to change the OS just to see the exact same Media Center software, but with fewer drivers available and missing other features we enjoyed with Win 7. There are more cons than pros to use it for this purpose, IMHO. Things may change as Win 8 matures, but for now I’m sticking with Win 7 for HTPC use. Win 8 is clearly aimed at the tablet market and not so much for desktop or HTPC users.
