Actually, most RETAILERS provide that sort of warranty on devices. In the case of cell phones, I think there's an FCC regulation that says you have 30 days to return your phone. I'll have to dig it up--but there ARE some guarantees/warrantees... but in ALL cases, you return the product. I'm not clear on his context, but if he meant that he should get some kind of discount off the device due to a poor experience, yeah--NOBODY does that. Caveat emptor, in that case.
