I challenge everyone to try a Mac with OSX for a week. I just completed one week of OSX use and I doubt I'll ever go back to using Windows at home. I am impressed with the improvements of Windows 7, but so long Windows. I'll only be seeing you at work.
I just got selected to Host a win7 party, hope my party pack is full of goodies. I challenge any mac fanboy to do half the stuff I can do on windows 7 on Osx, any of them.
And before you start, I own a mac, and I also use Linux, Mac can replace windows if : you have deep deep pockets, and only use itunes, browse the web, and maybe work on graphics or documents. Outside of that, it's windows.
