As I have said many times before, I hate bundled software, and I'm not afraid to say I don't care for the bundled crap Microsoft included but at least they give the option of uninstalling some of it now.
I am probably an enigma to Mac users as I can criticize both Microsoft and Apple and not feel guilty for doing so. If you find an Apple user criticising Apple, I wonder if they "strangely disappear". Hmmmmm....
Never been anything stopping you from uninstalling whatever apps you wanted to from a Mac. Not sure why anyone would want to specifically as they are all very good often even better than what others are putting out. But if anyone wants to they can. Sometimes they are so much better 3rd parties stop bothering to develop for the platform (ie AOL no longer develops AIM because of iChat).
