Maemo has been a Nokia touchscreen research project. The sliding keyboard, while not being 100% like the N810, still resembles it. The interface looks very much like [a] clone of Maemo although its way of dealing with applets is far better (other OSes and DEs have progressed in this before). The cry for disk space you can see back as well; with a 32 GB on-board. That might be the best of both the N800 and N810 SDs options. But I believe the development of N900, N97, and other touchscreen devices is somewhat paralel. One reason is because they all share some similarities (including TV out, touchscreen, ..). But also because of this news.
