How can USB 2.0 not be a priority?
Who says it isn't? Its just not ready yet.
So for me, what Hyperion says about AmigaOS 4.1 coming out of the beta, it is just exageration or simple marketing BS.
AmigaOS4.1 was already out of beta for AmigaOne and Pegasos II. It was still beta for the SAM because support for the SAM hardware wasn't quite ready yet and was released with a beta label attached. Now the SAM version is no longer considered beta.
