So, I am planning to buy myself a 21.5 inch iMac sometime in the coming week. I was looking at the refurbs, and the model i was interested in was 200$ under the usual price! So I think I'll go with that one. But my question is, will I notice any differences between a new and the refurb? And exterior scratches or anything? Thanks.
