Whilst they use ground-breaking advanced engineering, thermal design and materials and all that marketing garb, I feel merely like the pilot of an experimental aircraft about to tumble out of the sky at any moment.
The last three Apple computers I bought ended up being returned on warranty and the replacement sold due to electrical, thermal, software and quality issues. Fortunately we're covered here in the UK for 6 years with a small argument but none of the machines lasted more than 12 months in normal "at home" usage.
Now that's not exclusive to Apple but I don't expect to have these issues on a premium product. £183/month for a computer over its usable lifetime is a lot of money.
On the side I fix Apple kit for people. I recently replaced the screen on a 2008 MBP which had failed. It was a joy to do. I can't help anyone with a Retina MBP onwards though; warranty return only. That's a big red flag for buying any recent kit.
Second hand plastic ThinkPads now. Not had any problems for a couple of years and to replace the entire unit is less than a 2010 MBP screen and they're easy to replace bits in. #00 Philips and a swiss army knife and you're sorted.
