After looking at the HP Think Beyond event and the feel of WebOS community afterwards. The Pre3, Veer, and Touchpad all feel like Palm products instead of HP products. From the time HP purchase Palm to the HP event I don't think that was enough time for HP to create their own products. They just put their name on Palm already designed products.
The Pre's form factor is a good one but many more still can be explored. I hope HP comes around and produce a lot of different devices. I hope HP is working on touchscreen only phones with big and small sizes, the Pixi / Blackberry form factor, and how about a phone with a landscape keyboard as well. That could be a line of three new WebOS devices bringing new people to the platform.
If the HP Pre3 and Veer were both completely designed by HP I doubt these new form factors are coming soon because I believe HP would've atleast made a phone with a full touchscreen for a HP style of direct competition. Palm didn't design one because they wanted to stay with keyboard only phones which are fine but not all phones have to be.
