I'm going to rate the Orchard for what they advertize themselves as... a place that repairs and services electronics (specializing in Apple products).
Relative to this particular service, The Orchard is great. My son dropped our iPad and manged to beak the case, the crystal, and one of the buttons all at once. I thought for sure the thing was doomed. I called around and these guys were the cheapest by about 25%. Their turn-around time wasn't blinding (I think it was 5 days), but given the degree of damage, I was just happy that it was repairable and that the price was so reasonable. It was actually done a day or two early and they were good about communicating both once they found out exactly what was wrong and when it was done.
Based on the discussion I had with the tech when I brought it in and the discussion that the person in front of me had with the same technician, I could see how purchasing a computer here might not be the best idea. The guarantees are somewhat limited and what they can do is also a bit limited. But having said that, given the upfront cost of Apple products and what the people here are able to fix, the vast majority of the time it's going to be money well spent here to get your iPad/Pod/Phone back up and going again.
Overall I can't comment much on buying computers here, but I give them very high marks for their repair work and the cost effectiveness of that work.
