Somehow I must question those surveys. While quite a number of people I know use Windows, almost no-one I know actually uses IE as their default browser. Unfortunately severely insecure features of IE, like ActiveX, are needed to upgrade Windows. I'm sure Mozilla is capable of making its own 'ActiveX', but I guess they'd be sued as we are talking essentially American businesses. As we all know, it is rather difficult to remove IE from Windows. Clearly, the best option is the trend: Abandon Windows!
Any hacker can make their Firefox (or Opera) look like IE or any other browser. For instance, I don't use "Flash", but while I use FreeBSD, the scripts say its "Flash-10" on "IE-7" on Windows. Perhaps I should have some pride and tell the truth? I'm using Firefox, but I'm not sure that Firefox is what I have set in my proxy. Let me explain. Ikea, in Holland, gives you a 5% discount if you order with IE. Of course I'm not going to fire up Windows to order from Ikea! So, I simply "lie" and take 5% off.
If IE has up to 70% market share, its simply because Windows doesn't allow you to choose your browser like any other system does. If they did, they could just as well throw in the towel on IE. The percentage that use Windows is suspect too. Maybe some have it on hand just for an application or two? I know for a fact that many Windows desktops are running in Linux. (Doesn't an Xterm look great on a Windows desktop? ;)
Finally: (Taco) How many more people say they use Firefox on Slashdot than your logs indicate? I think you see what I mean.
