None that I have seen Frank (at least none that match up to the excellent choices on the iPad). And I have looked quite assiduously as I was considering a switch a little while back. Mainly because of the Motorola Xoom, with the larger screen, and the Android OS 3.0.
The Ipad and its AppStore plus its thousands and thousands of apps, is so far in front, it's really remarkable. And I read that demand is far out-pacing supply for the iPad 2.
