Hi.... its time for me to get a new Mac. The iMac appeals to me because of the great things I've read about it. I would like to learn more, though, about what it can do in the way of graphics, if anyone would be kind enough to point to good info about it. The thing that worries me most about the iMac, being an all-in-one machine, is what if something goes wrong with, say, the display, and I need to send it back for repairs. My computer is gone and I'm not able to work til I get it back. Can the hard drive be removed? Could I plug the whole thing into another monitor (even a CRT?) to copy files if I had to? I worry because I use my Mac for business and would not want to be caught without it.
