I do not own an ipodtouch, but now I know it won't be long before I do. I took an intro class this summer through the district so I was able to play. But now I see the endless ways that my students could use them. Some of the teacher favorites were wordbook, thesaurus, braintuner, blanks, whiteboard and wordwarp.
For myself I could use it for email, internet, web pages, games, entertainment,music and facebook. Wow, did I underestimate that little hand held piece of gold.
