Quote from the review:
“Samsung’s YEPP 55i is equipped with 192 MB of memory, presumably flash memory. Normally, we have flash based MP3 players coming with storage capacities of 128 MB and 256 MB, so 192 MB is a bit of an odd number. I think having 256 MB of memory would be a more attractive option but nevertheless, 192 MB of memory translates roughly into 192 minutes of music using a “standard” 128kpbs MP3 bit rate. That means you get to enjoy over 3 hours of music, which I think is adequate given the smaller size of the device.
The popular trend these days for flash-based MP3 player is small form factor and functionality as USB memory keys such as the Creative Nomad MuVo. At 25 x 81 x 21 mm, the size of the YEPP 55i is slightly bulkier than many of the newer flash-based players out there. However, the YEPP 55i includes voice recording, an LCD display as well as a built-in FM tuner, which explains the extra real estate required by the player. “
