We have been busy trying to get the first beta of Bonsai for the Windows Mobile platform ready for release. While it is very close, we are not going to make the June target. The good news is our new target is early July; this week, as a matter of fact.
In the mean time, we have a set of screencasts showing the new beta. As mentioned in the forums, this is NOT a feature-complete beta, but most of the core Bonsai features are working. Product release is still months away.
