Yeah, Mil, I feel terrible about your experience. Frustrates the heck out of me when I see that the repair chain isn't working...

However, do note that the tablets are produced in large lots, so even if you purchased your tablets weeks apart you could still be buying from the same batch (ie, made on the same day)-- and given that I expect the problematic tablets to be clustered, your experience actually makes perfect sense. That still doesn't make me happy, though.
