Just got back from Cebu GNU Linux Users Group meeting. I saw someone using Moblin. Three thumbs up! The UI is very intuitive, and will have no problems with mainstream customer adoption.
Meanwhile, Eeebuntu 4.0 is not even ready for early adopters. The installation stopped somewhere at around 95% and complained about failed GRUB setup. I'm currently downloading Ubuntu 9.10 Netbook Remix because my Eee is left with a broken OS. Let's see how this goes.
