I am looking to purchase a portable digital music player but have found myself completely lost when researching which one to get due to the amount of players out there and conflicting views etc. These are my main requirements: 1) Good battery life 2) Must have quality, loud sound output, with low signal-to-noise ratio etc 3) Drag-and-drop access file. I would rather the player pop-up as an external storage device in windows which I could drag and drop files to and from than having to install additional software. My budget is up to about £150 I suppose, with as much storage space as possible. Are solid-state devices more reliable and have longer battery lives rhan HD-based players? Thanks in advance!
