Yes, lots of them:

Why use mp3 when there is wav, you mean? Well, most people like the 1:11
size factor of mp3 (128kbit).

No, mp3 is for lossy compression only.

It can, but only if we find a skilled DSP programmer with the right tools.
There is no way we can to real-time (de)compression in the CPU.
