I agrea with Ashitaka. The main reason why I got into MD was because of travel - they run on a standard, non-proprietary battery which can be found anywhere and you can fit a lot of tunes on the media, which is inexpensive and rewriteable. I haven't noticed any problem getting it in & out of my pocket, but BDU pants (army fatigues) are pretty roomy - that might have something to do with it
