Reasons why I like IE6:
-Startup speed
I don't know if startup speed is better, but its performance in general, especially with scripting (i.e. most websites) is complete trash. This isn't a good reason.
-Interface simplicity and consistancy of appearance with the rest of Windows XP
How does Firefox, for example, not have "interface simplicity" or "consistency of appearance with the rest of Windows XP"? Even IE8 does 99.9% of the time, especially if you put the menu bar back on top (not sure how it is by default).
-When you launch a new process, it actually launches a new process
There's no good reason to need or want multiple processes of a modern browser open, unless it's a situation like Chrome where each tab is its own process. There's a lot of overhead having multiple instances of the same browser for no reason, and it doesn't help you avoid total crashes because 1) IE6 is going to be more prone to crashing in the first place, 2) modern browsers allow you to restore your session in the case of a crash anyway, and 3) at least in certain modern browsers like Firefox, a plugin crashing (which is the most common thing) won't even crash a tab, much less the browser instance.
-I do NOT seek out the kind of site that might try to exploit security flaws, so "better security" is far less of an improvement
You think people "seek out" those kinds of sites? They don't. Unless you stick to the same really tiny handful of sites and
never venture anywhere else, you
are at risk.
A lot of people have the audacity to think that they're somehow "above" people who get malware on the Internet. Nobody is. I
work in IT and I know I'm not. You aren't special just because you have common sense enough not to go on obviously-screwed-up sites, and you're
worse off due to the fact that your browser is insecure and antiquated.
Your reasons are few and petty and basically amount to excuses. You just plain don't want change, I think.
