I hesitate to say this for fear of provoking a fault, but although I wouldn't consider them especially good, they're not universal failures. I have a Pi running a house control and logging system that has an uptime of 230 days despite being largely unattended (I'm not on site - it doesn't get any special treatment). It doesn't have a read-only filesystem, however all logs are written to a USB stick.
