Summary: Cowon V5 media player can play MKV files, which is really hard with iPod Touch. (you need a third party app to play those files, and the performance sucks.) The real problem with this gadget is that the screen is very easy to be cracked, and the repair cost is almost $190 just to replace the screen. I still like the performance of the player, though. I'd just buy a new one with a screen protector and a shell.
