Firefox is OSS, while safari is of course not and run by apple. Why couldn't apple let firefox be instead of acting all MS and trying to battle them. Its not like Apple is playing fair, either, they are not allowing other browsers on their iPhone. Microsoft was attacked for preloading IE on windows computers, apple wont even allow competition.
Didn't MS get away with it ultimately though. They just got a slap on the wrist and a "we're watching you" threat.
So now, Vista has bundled defragger, RAM Disk cacher, and Security Suite...but just a bit more "careful" about it. hehe
