I can't run my favorite games on any OS after XP.
Every time I'm forced to "upgrade" I lose something else, and can't name a single thing I've gained.
I can name two things you have probably gained and it is a lighter wallet and a headache.
I have a shop with 100s of thousands of dollars of machinery that run on XP. When windows fanboys laugh at me for not upgrading I ask them to write me a check for all new equipment. They shut up right quick.
