Macintosh is great. Although I’m not using it myself, it has some great features. And as a Windows 7 user, I know Microsoft has tried very hard to make a nice and userfriendly OS. How ever there are some things missing. One really neat thing is the option to view all your opened/running windows or programs. In Mac OS they call it exposé. Now in Win7 and Vista you can have it as well. But here it is done with an application called Switcher. It is available for a while, but I never heard from it before. Very handy, completely cusomizable and free.
