Apple's Customer Service = Excellent
I have had nothing but a fantastic experience with Apple's Protection Care tech support team.
That said, I should mention that I am a graphic designer, a faculty member of a university that works closely with them to develop computers custom-made for our students, and actively attempt to convert my pc-loving art students to MAC users.
I have called Apple with a variety of complaints, with my 4 button pre-click wheel ipod to my clamshell graphite "hello kitty" laptop to my current (and hopefully being replaced after the expo) powerbook G4. they have been anything but picky about what they will and will not fix. when you explain to them why those pixels or the persistent battery-death or whatever the problem is... and why it means so much to you - as an Apple customer and lover, they are much more willing to help you out.
I think that it probably all depends on who you talk to when you are making the Apple Care claim, so if they don't seem to understand why 8 dead pixels will make any web/print designer crazy, then thank them for their time, hang up and then call right back. It might take a few tries, but eventually you'll reach someone who will care about your computer issues as much as you do.
I sent my last request in 8 months ago. Things may have changed since then, but they could not have been nicer.
And --- the Apple Care Protection Plan is a total no-brainer decision. Period.
