I love my C2D iMac but the time came to upgrade, so I anxiously awaited the new iMacs, but when I found out you couldn't upgrade the RAM yourself on the 21.5" model and the cost to buy one with 16GB and a Fusion Drive (must-have option IMO) came to $1749, I just couldn't do it. I was devastated and felt very frustrated. So I begin re-evaluating my wants vs. available options; the Mini has user accesible RAM, relatively easily access to HDD's/SSD's and even kept a FireWire port on the new model. Hmm... I already have a keyboard and Magic Trackpad.....I can get a decent monitor for ~$200. The mini it is, and I can't wait for it to arrive. I put this out there because I have been noticing quite a number of people online mentioning replacing their aging iMacs with new minis. Has anyone else noticed this trend?
