I recently sold my old 24 inch refurb iMac. From day one, it was trouble, banding on the screen and image persistence, and the genius bar refused to help me, saying its part of the normal function. I opened it up and upgraded the hard drive (why not? The warrantee was worthless!) and despite the screen irritating the hell out of me, it was the best computer I ever owned. Next month I am looking at getting a newer model, and am considering either the base model iMac or a mid-range mini. A refurb base model iMac is the better buy, but while the Mac mini half the power and requires that I buy the monitor and keyboard etc separately, it is more modular so problems would be easier to handle. The most stress I would put it under is portal 2, but otherwise it just needs to handle the occasional VM, sync with my iPad, surfing, and some spreadsheets, and a bit of transcoding, so either of these machines would do the job. Another option is a refurb 11" MacBook air. I would get everything in one box, and to compensate for storage, the Mac mini on the living room TV already hosts a few hard drives for the whole household. The reason I don't like the air is because I already have an iPad and don't see the need for yet another mobile device. I love the simplicity of Mac, reliability, and interface, but their stubborn refusal to honor a warrantee is what's influencing my buying decision right now.
