Israeli electronics company makes slim products. Really slim. In fact, most of the products that the company produces would probably slip pretty comfortably into your wallet--hence their clever name. One of the credit-card-size products on display at CES today was the Telex Music-Player.

The ultra-thin player has a built-in USB dongle that can plug easily into your PC for simple music-file dragging and dropping. The card will charge directly from your computer. It also ships with a headphone adapter that slips right over the USB dongle.

The card is available in 2GB and 4GB capacities.
