you win some, you lose some
I get extended warranties on products that I take 'on the go'--laptops, portable gaming devices, cellphones for the first few months. I guess to further clarify I would only get the warranty if it included accidental damage. I was able to take advantage of the warranty coverage for my laptop and cellphone in the past.
For items like LCD panels, desktop computers, etc. I think extended warranties are rather useless. The problem with those warranties are the fine print limitations and exclusions.
If all extended warranties come with accidental damage coverage they would definitely be appeal more to consumers.
