An unexpected update started rolling out to the ASUS Transformer earlier today that brings the build number up to 188.8.131.52. Even more unexpectedly, this update reportedly includes Netflix support without requiring root. Of course, the official Netflix app in the Market doesn't yet support the Transformer, but you can grab the latest version here.
There is also a firmware update available for the dock, bringing the version up to EP101-0213.
