I actually cannot remember whether my iPod is an actual iPod or not. It's an itty bitty digital music storage thingy of some brand or other - I forget.
I am pretty sure it's not a Zune, but that's about as far as I can go right at the moment.
But I am kind of liking the idea of audio books...
I do know people who use Wii Fit...or at least have Wii Fit and have used it some. They all seem to like it, although I don't so far know anybody who relies
on it. For the people I know who use it - and I'm not saying they are typical - it seems to be something used to fill in the gaps in their regular exercise routine.
