Voice recording in WAV format is unacceptable

Other voice recorder manage to store recordings directly as mp3 files. So, it is possible. There just needs to be the will at SanDisk.

I think you’ve misunderstood me. 9 MB is for just one minute of recording. I foresee needing to record hours of speech before getting to my computer to transfer the recording. One working day of a seminar, for example, will take more than the capacity of memory in the model I purchased (4 GB). And this also means that I won’t be able to have anything else on it while recording long sessions (lectures, etc.). Converting WAV files of hundreds of megabytes or even bigger to mp3 will take a long time too. No matter how I look at it, the approach SanDisk has taken to voice recording is bad and unjustified (other small voice recorders are much better at it).
