Like a couple of other devices mentioned here, this is one of those almost-need-to-have things. It rips, plays and serves. There is a CD/DVD transport that supports ripping a CD to the internal 250GB harddrive. It can serve up to 4 concurrent streams and it can play DVD videos. Stylishly concealed on the front there are slots for memory cards and USB sources. It has it all… but why in the fury fires of marshmellow meltdown have they omitted lossless fileformats? It supports MP3 – that’s it.
