This is an early build, but PreCentral got their hands on a WebOS 3.0 beta emulator and they’re reporting that this build, while strong, is still lacking some features.
However, what we are seeing here is a robust, tablet-based OS that may make some of HP’s upcoming devices considerably more compelling. While find it dubious that WebOS will survive this decade, it’s still an important part of the mobile ecosystem and folks who don’t want iOS or Android will probably love it for the brief time it is here with us on Earth.
