Top-end Apple laptop? 4 or 5 years, easy.
Umm, I don't think so - it depends which part fails. Batteries, for instance, are known for a short life (that's why you can never get them under extended warranty), and hard disks run AFAIK a close second.
Having said that, I tend to have a machine cycle time of about 2..3 years so I never get the extended warranty - also because I tend to take good care of my machines. It makes sure it keeps running reliably (in my experience, if electronics fails it tends to do in the first 3 months), it makes it easier to resell, and it's in general much nicer to work with a good looking machine..
