Awesome. I have Ubuntu running on my P1620 and I have to say, the touch support is severely lacking. I have to rely on a halve-baked third party driver for the touchscreen, which stopped working after a couple of weeks.

Earlier this year, it was noticed that EFL (Enlightenment Foundation Libraries) was being used to bring Ubuntu Netbook Remix to ARM-based devices. Because EFL was designed and developed with computational efficiency in mind, it can be used to deliver rich-graphical user interfaces even in non-3D-acclerated devices such as ARM-based ones (or ARM-based ones without access to proprietary drivers). The eponymous project, Enlightenment, also provides a module called Illume which modifies the user interface of Enlightenment to work well on devices with small screens and/or touchscreens. As somebody who already uses this particular graphical environment on daily basis on touchscreens ranging from 4 inches to 12 inches, I'm very curious if Canonical is tapping Enlightenment's libraries for this effort. In my brain, there's kind of a strange “love triangle” going on here centered choice of toolkit and the different interface needs for the netbook and the tablet. On the one side, Ubuntu Netbook Remix itself defaults to the Gnome desktop which is built GTK+. There is a good but old touchscreen/small screen environment built on GTK+ that dates back to the Sharp Zaurus called GPE, but it seems totally implausible that Canonical would go anywhere near that. On the second side, there's QT which seems to be the currently “darling” of GUI application development framework for mobile and embedded environments, most noteably MeeGo. However, QT is most commonly associated with the KDE desktop which is the primary “competitor” to the Gnome desktop environment which loads by default with Ubuntu Netbook Remix. On the third side, there's Enlightenment which is the best in terms of degrading from a full desktop to a tiny touchscreen (both in terms of performance and scalability), but isn't really used as the interface framework for any of the major software like word processors and web browsers. It'll be interesting to see what turns up, but if I were betting I'd put my money on Enlightenment.
