I miss Windows XP / 7, everything went downhill after.
Microsoft, especially after Windows launched, has always been the poster child for greedy, monopolistic, anti-consumer business practices.
There's been different things through the years, games was a big one, but there's still the lack of any good remote desktop solution that's keeping me on Windows. I also haven't found a good replacement for Acronis TrueImage, ie incremental full-disk backups that run in the background, which has allowed me to be back in action in under 30 minutes when I've had drives fail.
