I was really looking forward to an MP3 player that didn't use proprietary hardware. The Sansa e260 promised that it would show up as a disk drive or enable synching to MediaPlayer. The instructions were sparse and I tried both methods. This ended up in the device being so scrambled that there was no way to gain control. It showed up as both full and empty depending on what I was trying to do (get back in control!) I couldn't delete and I couldn't add and it hung on most operations. Contacted support and they were quick to help. We tried upgrading firmware, downgrading firmware, and other esoteric tricks requiring some interesing mulptiple buttons at startup. Nothing worked and Sandisk offered to send another along. If it only took me one day to confuse it, I declined their offer and will purchase the product I was trying to avoid.
