I used it up till 2011. It had multiple top-cases replaced under the extended warranty, display CCFL was changed a few times due to flickering, disc-drive got swapped once, new logic board because the audio-jack was stuck on SPDIF, new power adapter.

The only device I ever got Apple Care on and I got thousands in repairs covered for free. This was from before Apple would just replace the entire device.

All my other MacBooks have been trouble free luckily.
