2007 Macbook Pro, identification string "MacBookPro3,1". Four logic board replacements, one borderline.
When I was in college I worked two summers and sold my old Macbook to pay for this beast; I also bought AppleCare. It was an expensive laptop, but it performed admirably; it was basically top of the line in its time. Then things in Half-Life 2 started turning purple randomly. It didn't take much longer until trying to play Team Fortress caused BSoDs once the GPU had a chance to heat up. Then it got worse - I could boot up, but the screen was dead. They ordered me a new logic board, and the champ was back in business. Fast forward about three months, and the game I was playing had random horizontal lines on the screen. New logic board, no problem. Actually, there was a problem - the first replacement didn't finish booting once before the GPU failed; this one could at this point give me a text terminal, but any graphics were right out. Fortunately, the shop was booting it up on their bench to demonstrate their repair, so they had a new board overnighted in the next ten minutes, and the next afternoon I had another new board.
The next time it gave out - three months and a week, like clockwork, I escalated my tech support call. I got a department Apple will deny existing, called something to the effect of "Customer Solutions". These exist above first-line tech support (who are fairly knowledgeable and very useful), and above the engineers that they turn to when first-line efforts fail. They offered me a new laptop, with "like for like" - nothing worse than my old machine, except I lost the ExpressCard|34 slot on the 2009 model they gave me; while I'd like a USB 3.0 port, I must admit the ExpressCard slot mostly held an SD card adapter.
After that, I tried to get them to take the aftermarket hard drive out of my defective machine and put it in the new unit. They wanted to charge me $150 for the privilege of doing the deed without voiding my warranty at the local Apple store, and (remember: college!) I didn't have the money. I was about to leave with a broken computer in the hopes that I could work something out with phone support, but as I was packing my computer to go, the third-line person escalated my case. Again. I gave them the name of the store manager, and they hung up. She disappeared a few moments later after taking a call on her two-way radio. Ten minutes later, she came back looking rather startlingly meek - having started this day long escapade being painfully stubborn about this "nominal" charge that was nothing of the sort in my collegiate financial condition. She also had a laptop box in her hand, and told me she would have my hard drive in my hands more or less "immediately".
My takeaways?
Apple corporate was willing to grab the manager of their flagship store (at the time) by the (metaphorical) balls, shake briefly, and tell her to sit down and shut up or else.
Apple corporate was willing to face this problem head-on, and stands behind their products.
Apple has some bad apples at the local level (and it came out that this apple store was known as the least friendly in town, when I spoke to an Apple employee).
The unibody Macbook Pro is a downright pleasure to work on, once you get past the Loctite Blue.
The 2007 Macbook Pro used Kapton "space tape" to keep some internal parts in place.
AppleCare is worth its weight in gold.
The 2009 model really should be considered to have a user serviceable battery, as it's an easier swap than the hard drive; I just think they didn't want people trying to change their batteries on an airplane, or something similarly stupid.
Carrying around an unprotected MBP battery now is something similarly stupid, as they're almost as fragile as bare cells.
While talking to the Apple rep who specced out my replacement system, it came out that only 15% of users used the ExpressCard slot, and around 90% of them used it for a memory card reader, but I still want USB 3.0 now.
Unlike other laptops, the unibody Macbook Pro has easily cleaned fans.
