I am still learning it.
I am finding the app AutoStandBy is messing with it..
I get a big battery drain

I seem to get a zillion old episodes

(haven't figured how to zapp them away in one hit)
I seem to be downloading a zillion episodes (that is fine!

)
I have found the setting to leave 1 gig on my 16 gig memory card..
I am TOTALLY in love with it!!! Its a real 'life style" event for me..(not kidding) I can catch up on topics related to my (self employed) work while doing other things.
I am catching up with a zillion gadget / web 2.0 / technology shows and trying to 'hypnotize' myself into GTD methodology by listening to a zillion Getting Things Done podcasts..
I seem to be able to totally filter out podcasts when something more important occurs in front of me.
I am listening via a mono (one ear) BlueTooth earpiece.. so as not to disturb other people around..
