I made the plunge this weekend and got a 27inch iMac. I have never owned a mac before so this is a whole new world to me. Im sure there are a ton of cool things I can do but I get mesmerized by the screen! So I have a couple newbie questions: I bought this large screen and mac to be my office desktop but I also want it to double as a TV in my den/office. What do I need to do to hook a cable box or something up to it? Is there a guide anywhere on this site of must knows,ins and outs for newbies, things like that for a windows to mac convert? Thanks for any help and really looking forward to exploring the site more and learning about my new "baby"
