Once we have the district fully wireless which is right around the corner, we'll be using iPod touch devices and iWalkthrough <http://www.iwalkthrough.org/>.
(sorry to respond to the list, but I'm also testing that I've got my list-email issue figured out!)
Did you evaluate other observation software? Why did you go with iWalkthrough?
I'll check out the link, thanks!
