If the training information from HP is to be believed, the World should be awaiting the arrival of WebOS Netbook that goes along with WebOS Smartphone and Slate devices.
Based on the WebOS 101 section, it shows 3 devices (Slate, Smartphone, Netbook) and with the comment about running WebOS on them. And there is a mention that these devices might come soon enough.
Engadget is hoping that it could appear during the MWC in February. What do you think?
