Do anyone know the life expectancy of USB Flash drives. I've heard rumors that they wear out after so much usage. Any Input?

The flash memory inside a pen drive has a limited write/erase cycles on the order of 1,000,000+ times.
No limit on reads. You do not want to run an OS unless it is one designed to run on a pen drive or something similar to a liveCD.

So yes you can wear one out.

It depends on the device but here is a specification for an Intel device.
Minimum 1,000,000 Program/Erase Cycles 20 Year Data Retention at 125oC

My answer to the question is correct.
It depends on how you use the device and for its typical use as a backup device I wouldn't worry about it.
