Personal experience - MagSafe user since April 06 across 4 different machines. Never had a problem with a damaged or frayed cable.
Only problem cable I've had was the 30-pin for my iPhone 4, the insulation started to split at the USB end after 4 years. So I taped it up.
Treat the cables with respect and all should be well.
