Oh, then I can take the Honeycomb source code and do whatever I want with it?
Oh, wait, I can't? Then how doesn't this make Android 'closed source'?
At least with Gingerbread (2.3), the source code wasn't available until it was officially released (on android.git.kernel.org). A few days after the release of Gingerbread, I could see the gingerbread branch.
Honeycomb is still not released as far as I know. When it's released and the code is not available, then we can talk.
Until then, it like a G5 powerbook :-D
