Do you recommend getting an extended manufacturer's warranty when buying a laptop?

Do you recommend getting an extended manufacturer's warranty when buying a laptop?

My current older laptop is still going and didn't die on me due to not having a warranty, but it was fairly cheap so I wasn't concerned with the potential of it having any issues.

I'm considering upgrading to a Sony or Lenovo Thinkpad with Windows 8, and wondered if I should bother spending another $150-$200 on a 2 year warranty.

What are your thoughts/experiences? Thanks.
