I'd be more willing to bash Microsoft if every platform didn't have its own heaping piles of stupidity. There are plenty of things about Amiga, various builds of Linux, MacOS, Be, QNX, OS/2, and all the other OSes I've used that drive me nuts.
There are bugs in Firefox that have been aroud since v0.8. As I type in forums like this one, the Alt key gets "stuck" and causes tons of hotkeys to activate instead of normal text. Does anyone fix this? Hell, no... they've got more features to add, first. Does anyone get mad at Firefox? Hell, no... because it's open source and better than IE, and that makes it perfect.
I think the whole computer industry went to hell in the mid 90's.
