That's it.

From Wednesday night through last night, my MacBook was working perfectly. It wasn't shutting down unexpectedly, and thus my fear of having a still-defective computer was melting away completly. Until this morning. Now the problem isn't the MacBook shutting off; it's that it won't even start up! If I had another two weeks to dick around here, perhaps I would let Apple have another go at it. But I don't, and I won't. I've heard that Apple has replaced MacBooks for people due to the paint job wearing off. Surely they'll consider a replacement for a computer that won't even start. Hmph.
