I squeeze into my POD.....
Charger for Zaurus
Charger for phone - phone's on my belt
Spare batteries for S1
If I need my laptop, I take my Hartmann briefcase as well. Often I get everything in there but leave the camera at home.
Edit: I decided this was too much of a squeeze - I have to take the Zaurus out of it's case and pretty much force it in. Found a super price on Podzilla so that will make things easier.
