I bought a Nokia N810 from Amazon. Actually, there are not any shopping malls selling N810 in Korea so I had to buy an N810 from the oversea shopping mall. Anyway, I am very satisfied with N810. It may be my favorite toy.
N810 uses the Maemo platform that is based on Linux 2.6, GTK+, Matchbox and other open source projects. Scratchbox is used for its development environment that supports a cross-platform development environment. So the users can implement an application without knowing how to use a toolchain for specific target devices. In addition, we can easily install applications from the repositories using Debian packaging & repository system.
I think that it's a truly open mobile platform based on Linux. Because Nokia gave their governance of hildon to the GNOME community.
First, I'd like to build XUL Runner and run Fennec (Mozilla Mobile). It seems that it could run on N810 and Windows Mobile 6. So I'll check the status and give my feedback to the community.
