Call me a fanboy, but Foleo is a visionary product much the same way Palm Pilots were back in the day. No one understood it, everyone thought it was stupid, but years later, you see people having one using one and loving it.
Foleo has the same things that Palm Pilots had going in the beginning... simplicity of design, simplicity of use, and third party support... Foleo's main strength is its being linux... dont be surprised to see that 10 years from now, you'll see as much apps for Foleo as you see for Palms today.
Foleo is more of a potentially important product... Hawkins vision is a smartphone centric world, where you do everything with the smartphone... but limited by its small keyboard and/or screen... thus he makes this extender for the smartphone (yes he sees it supporting th iPhone as well) which can also serve as a standalone Linux laptop just enough for your everyday mobile computing needs...
To quote Hawkins: "The further out you are, the more people have trouble understanding. It's hard to go back in time, but when we did the Pilot, there were a lot of people that thought that was a stupid idea. I mean a lot."
