There are usually some sacrifices that have to be made when you want to make your devices a little lighter, a little smaller, and a lot thinner. If you’re not a fan of bulk, the Samsung M3510 may be your cup of tea, because this “full blown music phone” measures a mere 10mm thick.

On the tune-pumping side of things, the Samsung M3510 offers a 3.5mm headphone jack, an accelerometer for motion-based music playback controls, FM radio with RDS, and microSD expansion. There’s also a 2-inch QVGA display, along with Samsung’s usual suite of other applications.

Proposed pricing for the music phone is rumored to be around 200 to 250 Euro, which works out to $315 to $390. That doesn’t make it the cheapest music phone on the block, but how many are just 10mm thick?
