But that is squandered by piss-poor programming and stupid visual gimmicks.

I had to return to Windows as a daily work platform after a long time away (on Macs). I already knew that it had devolved into a grotesquely defective, regressive parade of UI blunders and deleted functionality... but its actual performance is TERRIBLE. I'm waiting for simple operations that I wouldn't have expected to wait for 20 years ago, even on bog-standard office desktop machines.
