Earlier quoted context omitted.
My 2 year old X200 has 1.3 hours battery time, decreasing rapidly. The display plastic is broken, the camera is broken and the mouse tracking nob is broken. It's the worst piece of laptop hardware I've ever had (compared to older IBM Thinkpads, DELLs and iBooks, Macbooks and MacbooksPro).
Strange. I never had any problems with my Thinkpads, but my Macbook has had several. The plastic casing is brittle and just breaks off after a certain amount of time, the battery died and needed replacing, the hard drive died and needed replacing and the power supply died and needed replacing too. Seriously considering getting one of these new Thinkpads and sticking Ubuntu on it. Maybe the T420 or T520.
This is apparently a known issue with certain models of the Macbook. I had mine replaced free of charge as well, even though I'm out of warranty. Apple is aware of the issue and I'm happy that they at least replaced my case without a fuss.
