It's the first time I've bought a Mac at the beginning it worked very slowly, I asked for technical support and they helped me through chat and now it's normal but sometimes again is slow. As for how it looks, it's perfect, I love the size of the screen and the sound and the camera are very good.

Decent Apple computer for the price. Widescreen is important.

I purchased an Apple certified 21.5" iMac from Best Buy. It's the first time I purchased used computer - but needed a good deal to replace my Mac that could no longer receive updates. The computer is perfect and the communications that I received were professional, timely and kind. It's a great value!
