This is my fear. I'm a Mac girl... and dread it dying, mostly since they don't make my 17" laptop anymore.

The HD failed this summer, and I lost some things. Mac fixed it, and it's been good since then... but I'm sad. It will not be here long. I have an iMac, which is old, but completely usable, and almost like new, even at 6 years old. My kids use it for school basically. I could use it, and it is large enough but I dislike the thought of being stuck in the guest bedroom to use the computer.
I wish great things for your computer and that it lasts and lasts!
