Speaking of data loss, it's fucked up that Apple doesn't give a shit about your data.

Ages ago I shipped my iMac to them and it came back with a new HD. Hello? Maybe include the old drive so I can attempt to recover the data? I lost a year's worth of photos and a bunch of personal documents. This is when I started doing backups.

That really sucks, but they absolutely do tell you to back up all your data before sending your machine in for service. Involuntary hard drive replacements aside, your package could get lost or damaged in the mail.
