I want to try out OSX. However I don't have a Mac that is "certified" to handle it. I will be in the market for a system soon and I'm not considered a "switcher" as I keep an open mind for all computing platforms. I figured I want an iMac type since everything is in 1 system and easier to use. I don't want a super sluggish system but this isn't going to be something more of a tinker machine/ internet serving system. Like I said, I just want to try it and get experienced in it incase it comes up in my job. What is recommended?
