The Clip? What are the pro’s/ con’s for using it?
Extremely small & compact. You might also consider the Sansa SlotMusic player. It’s only $20 so it’s no huge loss if it gets stolen while you’re in the shower or broken, but it only operates off of a Micro SD or SDHC card; no internal or on-board memory. It also has no display to break and uses a AAA battery. 2GB cards are a dime a dozen these days, and they will hold enough music for several work-out sessions without repeating.
Both the Clip and the SM player have clips so that they can be attached to your clothing, and weighing vitually nothing, they shouldn’t come un-clipped slamming into the weight machine.
