I think I'll be fine battery wise. I have many charging options. I installed an after-market player cable in my car which charges iPods while they play through my car stereo. My JBL external speaker charges it as it plays. Then of course I have my laptop while at work and my desktop at home. The only time I see myself away from a power source is while bike riding and that wouldn't be more than a couple of hours.
Does the iTouch battery have memory issues (must fully deplete the battery and recharge a few times)?
