Samsung had to pull out all the engineers in their design department to pack such an array of functionality into a device that won't even cover a deck of poker cards. I have to hand it to them for jamming everything this device, and still keeping it easy to use and completely functional. The video quality is actually quite good when set to the maximum resolution and quality, the MP3 player works as stated, the voice recorder is superb and having the potential of having a 2.5Gb portable hard drive in your pocket when you take advantage of the external memory capacity alone is a lot to ask out of one product.
