Surgery
Before I even booted it, I thought it would be convenient to put in the upgrades I bought. Putting in the AirPort card was a snap. The memory was less easy; I had to take off a small panel held in place with #00 cross-tip screws, and they were hard to unscrew. I nearly stripped one of them, and finally resorted to turning the screwdriver with a wrench. Everything worked out in the end, and I got to open up the lid.
