Dear Apple: fool me once, shame on you; fool me EIGHT TIMES, shame on me.

I give up.  I have owned eight of your Airport Time Machines.  Eight.  And the number of them that have failed catastrophically?  EIGHT, including the replacement one that the Apple Genius gave me yesterday (w/o a receipt, even though I asked).  I have no way of returning it for credit now, so you've cost me a couple of hundred bucks--or over a thousand bucks, if you count ALL of the ones I've purchased.  NO MAS.
