The 3.5mm jack means you can plug it in almost anywhere. I tried it on my desktop, ipad and the N8 and the sound quality is excellent. I know its mono but i think if you have two of them you can turn it to stereo. Couldn't really try as i only had just the one to try.
The small form factor also makes it a bit easy to carry around on your travels. Who needs a big boombox when you can carry your phone and the MD-11 for all your musical entertainment needs.
