I am a late adopter, I prefer to wait until a new OS is out for a couple of years and have had a couple major updates before I will even consider it. If I have to get a new computer then I might make a different decision, but I prefer to give them a chance to work at least some of the bugs out.

As far as browsers are concerned, I find I have more luck with Chrome than even Firefox these days. I am a government employee and that is my browser of choice. IE is the current supported browser in our enterprise and it still has problems accessing PDF files on websites - but I've no problem using Chrome - so I do. FireFox is better than IE where this is concerned, but I still have some trouble with it.

Most of our enterprise is still on XP, my agency only just moved to Windows 7 as a test environment a couple of months ago - mainly because the new version of the model I run will no longer operate in a 32-bit environment. I really like Windows 7 (the first time I've been able to say that about any Windows OS) and have no intention on moving to 8 in the foreseeable future.
