I was driving to NYC yesterday so I didn't see the offering on Woot but...
I hope some lower-end android devices start to show up soon that get wide enough adoption that some of the developers doing root version of smartphones will support them. I got a 7" one about a year ago running Android 1.6 for only $150. Sucked that it was a mixed version of the OS, so some is English while many of the apps/tools where Chinese. (but it did have a color touch screen which was pretty cool)
I think it would be cool to have low-cost input devices for the ADK hacks.
