I have been looking into getting a Mac mini and Apple just recently put a few in the refurbished section of the Apple Online Store. Are these computers of good quality? I don't want to be taking this to the Genius Bar all the time just because I sought to save a few bucks by buying refurbished. I have been getting refurbished phone replacements from my local Verizon store that break all the time, but I am guessing that Apple makes a bit of a better product than LG lol. Thanks!
