Honestly, I've never found Macs easy to use. I struggle whenever I find myself having to operate one. This is probably just because the first computer I regularly used was a PC, but I've always found the Windows interface to be more intuitive (ie, the max/min/undock button triplet on each window, right clicking an object to do things other than opening it, etc).
I also love my computer's customizability. If I want to upgrade to 1024mb of RAM I can get two 256 cards off eBay for $70. My computer stopped running about a year ago--I took the cover off and immediately found the fan on my video card had siezed and fried it. New one goes in, plug and play, its like a whole new machine.
