Jan,

Just about any small audio recording device that you pick can do that sort of task. Fidelity is not a big issue there, but things such as ease-of-use, built in mic, built in speaker plus earphone jack, size, and, of course, cost would be the key factors.

But here comes the biggie:

*I found out by trying the same thing that the ideas I had that I could not remember weren't worth remembering.

Likewise, the good ideas don't need to be recorded in order to remember them.


YMMV
