Hey Guys, Any thoughts or fears of the Tivo Mini failing? We all know with TIVO units, the percentage is really small and it's usually fixable by swapping hard drives. But the Mini's longevity is unknown at this moment, and there is no hard drive. So failure would basically mean the end of it. Also, does the Mini have basic functions without subscription? You know, just to make sure I don't get a lemon prior to slapping lifetime on it.
