My computer is back! I thought it would be tomorrow, but it came early. I went up to Flatirons as soon as the boys woke from naps.
My trackpad was acting wonky for about a week, then it stopped functioning all together. I took it in Friday and they shipped it out to the warehouse. Since I have Applecare on it they also replaced the battery, the logic board (?), two memory cards, as well as the trackpad. Hooray! I'm in tip-top shape again.
The previous post was re-edited after it failed to post correctly from my phone.
