I am on a 24" iMac right now, have had it for 2 years, never so much as a hiccup. The screen is amazingly accurate and stunning, my photos look exactly like what I remember shooting. I have been using MACs for about 16 years and never had a virus or needed to load a driver or anything else, plug and play. I have downloaded over 6,000 songs and movies from a variety of sources and again, no problems. Did I mention that I have no virus protection?
My brothers and I have done extensive illustration and photography retouching, production of books and everything else you would do on a computer, no problems.
The standard line from Windows users is that hackers wouldn't bother to go after Apple products because they aren't big enough........ seems like someone would have gone after them by now just to shut a person like me up.
This is what you can get as far as the latest 27" iMac.....

Many might say that is too much to pay but you are getting a stunningly good looking computer with a very reliable Operating System that makes Windows 7 look like last decades interface........ the wireless mouse is the absolute finest mouse I have ever touched and the wireless keyboard works flawlessly. It looks great on any desk but you can also take the stand off and put it on a swing out mount on the wall.
I spend a lot of time on my computer, it's worth every penny I paid for it.
