Maemo provides a much different focus - the site doesn't deal at all with the potential of remote X on the 770. For my part, as someone who views the value of the 770 in the context of better competing in the vertical market solution biz, I don't feel comfortable even talking about the concept of apps that are not 100% GPL over there, whereas here anyone with my viewpoint at least can hint at the idea. In particular, vertical market apps as a business is where Linux doesn't seriously compete yet, much less dominate, and the apps that will change this simply have to be a hybrid of GPL & proprietary for now because they have to be created and compete within the context of working revenue models.
The last news article at Maemo is October 26. I don't see a welcome mat over at Maemo for that, and I don't see anything in their list of X software except programs like 'Joe', an ascii-text screen editor and VIM. That may make some people happy but it doesn't float my boat. Maemo has its place but the action, clearly, is here, especially now that the HowTo Wiki and Software sections have been added.
