Very happy with my purchase. The computer arrived well packed and in pristine condition. The mouse and keyboard are aftermarket and not too thrilling, but the iMac itself is gorgeous and totally usable. As a lifelong PC user, I'm impressed with the longevity of the Macs, as well as the quality. I was easily able to upgrade to the latest operating system.The computer is a little slow at 8GB of memory, but they are upgradable. Unfortunately with the 21.5 inch models, it's very involved and akin to performing surgery since the memory modules are underneath everything else. If I had known that, I would have gone with the 27 inch model, which are easily upgradable via a back hatch. Too bad the 21.5 doesn't have that feature. Other than that, it's a beautiful and useful computer, even 5 years after its release date.
