I just got hold of this cute little thing, which is as big as the mouse-pad I use with my desktop. And yes, it runs GNU/Linux (kernel 2.6.21) and KDE (version 3.4.x, not 4.x)!
The one on the right is the ASUS Eee PC.
KNotes, KmPlot and KDE Task Manager
Mozilla Firefox and Kontact
Unfortunately, it could not import the photographs from my Olympus digital camera. It mounted the device correctly and gave the standard options to open it in the file manager or the picture manager, but there was no progress beyond that.
Apart from that it has been quite impressive in the 40 minutes that I have used it:
+ power on to desktop in 30s
+ multimedia keys detected
+ nice set of applications -- Thunderbird, OpenOffice.org, SMPlayer, Pidgin, etc.
+ unconventional, but intuitive user interface
+ they also seem to manage to ship codecs for restricted multimedia formats (which is more of a geographical/political/legal thing and not so much as a technical one)
The immediate objective is to set it up with a Vodafone GPRS connection for its owner (not me).
