For me the best e-book reader sofar is the iRex Digital Reader 1000S. It is not cheap, but it does A4 pdf and has no DRM issues. I need it mainly for technical papers in pdf format. But it also does e-books from Gutenberg or other source very well. Its main shortcoming is the very poor support of html.
It matters a lot for Classical music, less so for most types of pop music. Obviously it depends also on bitrate and recording quality. But I have never yet heard a compressed music file with classical music/ Opera which matches FLAC. In this day and age with the size and price of disk space there is absolutely no reason to use lossy compression.
I buy a mobile phone to make calls and send SMS.
If I want to take pictures I use a camera.
If I want to use a music player I will certainly not use an mp3 player but something with ogg or flac (Cowon is my favorite).
Cramming all functions into a mobile phone will just lead to poor quality cameras and poor quality music. And yes UI is also an issue.
To me it is just mobile phone companies trying to justify higher prices for their devices. It is almost impossible to buy a good mobile phone without all this extra overload that I will never use, even though I know perfectly well how to operate the thing.
