As to why, I can think of a few things:

- triggering recording at fixed time intervals, or based on some audio
event like raised volume, or based on some external event, e. g. for
syncing to a video camera
- implementing USB audio so the device can be used as an external
microphone. The recorders I've seen only output an analog signal.
- changing recording parameters like custom sampling rates or different
encodings. Commercial ones mostly do uncompressed WAV or MP3, but no
lossless compression like FLAC for example.

Other people probably have other ideas...

Last not least, I simply like the idea of being in control of hardware
I buy.

As to price: the DSO nano is a free/open source oscilloscope which
isn't expensive at all, so building free and inexpensive hardware is
possible. Actually, using the DSO nano as a base could be a good
start for a recorder, it has A/D converters, mass storage and
everything... Just no mics.
