I have a couple of MP3 players (including a CF-based one I use while running -- despite the buffer, MDs have not been good for that task), so MP3 support is not a major issue. I primarily use my MD for recording (both digital and analog). This includes digital recording of Internet streams. While I do not need the MP3 function for music (at least not this late in the game), it will be a major plus for me if the new generation has variable speed control for MP3s -- I have a ton of MP3 audiobooks, and, while I'll keep my MP3 music on my MP3 player, the speed control function will make the player perfect for listening to audiobooks with minimal transfer hassles. That said, I am in the market for a new unit, as the LED on my R70 was damaged recently. If not for that fact, I probably would not be salivating for one of the new units. I could probably make do with a display remote, but rather than spending $40 on that, I'll probably go for the RH10. The primary selling points for me are are the OLED and long battery life.
