portable storage

Thank you for this straightforward advice about standards, Aidan, and  
the rest that you advised.

I conclude from your deswcriptions and others provided by list  
memers, that for simple storage in the field, there is no inherent  
advantage to any particular hardware. Since an 8 gig card in the Zoom  
H2 Handy recorder will hold over a dozen hours of recording, which  
may be all that I'd record in a week, I think that I will equip  
myself with is a small supply of such cards for the H2. The H2 uses  
AA batteries, so power is no issue with it in my context.

The one feature of the iPod that remains viable for my context is  
that it is a portable playback unit, once the files are in MP3  
format, I assume. I have to have some portable way of playing back  
selected files in the field. Something I can carry through rainy  
weather and set up indoors or outdoors.

But other MP3 players seem to be much cheaper (and more so all the  
time), and hence relatively disposable should they get dropped in the  
sand or whatever. Maybe it's just a question of finding a model that  
is not too fiddly.
