I think the problem for Open webOS preventing them from backporting it to older hardware is the proprietary drivers. There was quite a bit of disappointment with HP when it was announced that Open webOS wouldn't be available for the Touchpad. I can understand their reasons but it does put more pressure on the community edition now. They are doing great things though, so theres little doubt a stable Touchpad version will be available soonish. I don't own a Pre but there seems to be a lot of love for it. I personally think webOS on the Touchpad has a beautiful and elegant user experience but is a bit of an arse to develop for so I'm going to wait until a stable Open webOS release to seriously look at its internals.
