I think the progress is so slow in some cases because even though MP3 is being called mainstream now, most people are still ignorant or very uneducated about it. I watched a report on ABC the other night about it and there was a informal poll to a group of college students about MP3s, and they all had used them (and all illegally heh) but I imagine that they simply could double click on the file. The mainstream public is still not computer literate enough to deal with hooking up a lot of MP3 players and loading songs into them. I think companies are still a little bit nervous about creating very advanced MP3 products because they arent sure if they would be accepted, and also a lot of time has to be put into them to make them as simple to operate as possible. Just my 2cents.
