I am happy with my new 24" 3.06GHz which I bought last Friday night. I switched from Windows. I am still learning everyday but the more I use the machine the better I like it. My wife uses a PC but tonight she worked on Quicken (Mac Version) on the new computer and she did just fine.
My son enjoys Grageband and we have installed Final Cut which he uses at school.
I am going to buy a Wireless mouse just not sure I want the Apple one or perhaps a Logictech.

My 24" Mac is now 1 week old and I bought the Logitech S510 keyboard and mouse for it a few days ago. Couldn't be happier. Much easier to type as the keys are closer together and the mouse works 1000x better than the Apple one.
