Tell me about it.
No, I don't have a blog anywhere about it, but I can tell you exactly what was wrong with each one:
#1 (15" CoreDuo) - SuperDrive DOA. Returned next day for #2.
#2 (15" CoreDuo) - Extreme screen flicker, loud CPU whine, random shutdowns from overheating, LCD inverter hum. Returned for refund, waited for Core2Duo which was coming soon.
#3 (15" Core2Duo) - Required logic board replacement after two weeks. Actually, I still have this one and use it as a secondary laptop, even though it also has the horribly grainy screen that I can hardly stand to look at.
#4 (17" 2.33 C2D) - Battery exploded after 12 days. I just asked for a new battery, but the store wanted to replace the machine, citing concerns about the SMC. Traded for #5.
#5 (17" 2.33 C2D) - Significantly warped bottom casing. This one wouldn't sit flat on any desktop surface and would wobble when typing. Extremely uneven LCD backlighting. Exchanged for #6.
#6 (17" 2.4 SR hi-res) - Required logic board and AirPort card replacement after one month. Replacement logic board failed upon initial boot, they tell me. There were also some minor backlighting issues, but I wasn't concerned about that. Given the trouble, the store offered me a refund even though I was out of the 14-day period. Took a refund and sat on the money for about a month. Then used some of it to buy #7.
#7 (15" 2.2 SR) - Samsung LED-backlit panel with significant yellowing. Took back to store to exchange for #8.
#8 (15" 2.2 SR) - Opened IN-STORE. Samsung LED-backlit panel with significant yellowing. Exchanged on the spot for #9.
#9 (15" 2.2 SR) - Opened IN-STORE. LG LED-backlit panel with extreme backlight bleed (bottom HALF of the screen). Asked the manager what he thought about it, he said I shouldn't accept that. Exchanged on the spot for #10.
#10 (17" 2.4 SR standard res) - Paid the difference from #9 and took this one home. Uneven backlighting immediately noticeable but was willing to live with it. SLIGHTLY warped bottom casing prevented the laptop from sitting flat on my desktop surface. Frequent kernel panics, system hangs, application crashes (iPhoto, Safari, Finder, ...), to the tune of several times each day. These problems persisted even after two clean re-installs (erase & install option) of OS X. Intermittent trackpad malfunction & a few significantly misaligned keys. Might have lived with all this, except that the frequency of the crashes made the machine basically unusable and pointed to possible hardware defects. Exchanged (after having to fight the manager on this) for #11.
#11 (17" 2.4 SR standard res) - Have had this one for two weeks now, no problems so far. The screen is slightly more grainy than my past 17" units, but it's about like a last-generation iMac or many 23" Apple Cinema Displays I've seen in terms of grain. Only noticeable very close to the screen, otherwise perfectly acceptable. Nice, even backlighting (still a slight ~1mm bleed at the bottom, nothing to get upset about on a MBP). No problems that I'm aware of.
There you have it. Statistically unlikely though it may be, that's my MBP history. All of these were purchased at my local Apple brick & mortar retail store.
