Still pretty good, though.
One of my home built Linux machines, an STB that serves as MythTV frontend in the living room, died within a year. This was a small form-factor mini ITX, with non standard parts. After dismantling it all (yes, all) of the capacitors in the PSU were bulging, and failing. The online importer failed to respond to complaints. In the end I simply dug out my soldering iron and replaced all the capacitors with specimens of a higher rating. But without wanting to sound arrogant, how many average punters could have done that?
From about about a dozen or more specimens of Apple devices, iPods, iPhones, Mac Minis and iMacs, over the past decade, the only disappointment was an iPod touch that failed after two years, and a dodgy battery in an iPhone 6s. Apple replaced that dodgy battery last week, iPhone nearly four years old, for just £50.
