It's kind of embarrassing to see that almost as many people are still on a 13 year old (!!!!) operating system as there are Windows 7 users. It's even more embarrassing to see that there actually are people out there who use Windows Vista! And also, don't forget that Windows 8 came out more than a year ago.
Dude, Windows is expensive. I'm not embarrassed to be still on Vista. Why are you embarrassed for me? I don't have a disposable income. Congratulations if you do.
Buy me a 64-bit Windows 7 Professional license and I will upgrade my Vista machine. I'm dirt poor and migrating to Mac and away from PC. My PC just isn't that critical to me any more. It runs what it runs well enough to run away from it when not playing Windows-only games on my also greatly outdated nvidia 8800gtx.
