Apple is starting to be a bunch of fucks. They are trying to pass their browser through an auto update for iTunes. The option is already checked, so if you do not want safari on your computer, make sure to uncheck it. I have been trying to use Firefox but it keeps locking up on me, the session recovery is useful in that regards though.
As far as MS vs Sony, they are both out for profits and do not care who gets in their way. This goes for all companies, Apple, Nintendo, and dare I say it....Google. I have never had problems with M$ products(I haven't used Vista though, but I do own a Zune that I won through Live Search Club and it is fantastic) and as long as they keep delivering awesome ass games to the 360, I will be with them in this and next generation.
