Are there any devices that are like an iPod Touch, but run Android?
Nothing of quality yet (at least IMO).  Archos has just announced a new product line of Android tablets and smaller devices.  Also Samsung has announced the Galaxy tablet (http://news.cnet.com/8301-17938_105-20015395-1.html) that looks impressive.

I think you'll have a ton of options around the Christmas shopping season.. Keep an eye on Engadget, not a day goes by they're not showing another "leaked" Android tablet.

ETA:
here's a link to the Archos 101 tablet.. Looks pretty impressive:
