Portability YES -- Especially for Gyming and to carry it everywhere with along my Phone. 16GB should be enough for me even after expansion. Rugged and tough, should be able to withstand bumps on table tops and the possible wash cycle Don't want Video, have the phone for that and music takes up most of my phone's battery life. 3-4 hours a day at work it keeps playing music. I won't be using any expensive IEM but I expect the sound output will be better than an Android phone atleast ? Now given all these requirements .. tell me the following 1. How easy is it to organize music on this ? 2. Does it charge through the Laptop USB only ? 3. Battery life ? 4. User Interface of the Player ? Finally the cost and how to buy it ..
