I'm still using XP, and it still works as well as it ever did. Of the newer Windows releases, I think 7 is the most palatable, but I'm not going to go nuts trying to find a copy at inflated prices.
Classic for them to stop sales of the Windows version most of their core users prefer, because it might cannibalize sales of what they wish people would buy. They're getting paid either way! Follow the market! But no, it's more important to protect their ego.
Their head is deep in the sand. They really need to start taking their customers seriously instead of laughing them off and trying to dictate. For all of Microsoft's past dominance, they seem determined to sink the ship. It can and will go down if they don't adjust their attitude. As Windows declines, everything else will follow.
Microsoft apparently thinks they don't have a future without mobile devices, but mobile devices don't want Microsoft. In the process of this battle, they continue to ignore and alienate their desktop users. To keep Windows revenue alive, they cling to the outdated 1990s era belief that people need to "upgrade" their computing environment every 3-5 years. People are rightfully resisting that more and more.
Worst case, I just use XP and/or Linux for my everyday OS and use some new bloated security nanny release as a glorified game loader.
I wish XP64 had been better supported, instead of ignored. If XP64 was a current product, I'd pay full retail for it right now.
