Interesting, can I ask what kind of work you do? I'm assuming programming, what kind of programming do you primarily do?
Actually, I'm just a teacher/office admin/etc for work - by passion and hobby I'm a writer but that hasn't turned into money and likely never will.
I don't do programming and never have, the closest I ever came was a brief scrape with BASIC back in the days before Windows. I do some web design, but not too much anymore because I don't do Javascript and I don't like off-page CSS (I sometimes use inline, but that's about it).
I only use a 32-bit OS and a 32-bit processor for Win7. If it doesn't work in x64, you've just given me a reason to never "upgrade". Then again, if my computer didn't throw a hissy fit over it, I'd be using FreeDOS as my primary OS. Either that or just get an old MS-DOS 6.2 installed.
