And by testing out IE, you ran it once,remembered its a bit pish and then downloaded and installed Firefox, or even Chrome?!
By the way, the reminds me, I read the other week that Microsoft will not be including Internet Explorer in future releases of Windows - after they got so much legal stick about it etc, (despite that, they are now getting bollocked for NOT including it!) but if there is no browser, how do you get on the 'net to download another one?! I doubt Microsoft will include installers for their main rivals in the OS!!!
