FWIW, KDE today offers three workspaces built on Plasma, Plasma Desktop, Plasma Netbook and Plasma Active. These offer increasing levels of touch-friendlyness, but even Plasma Desktop, though built largely around mouse control, is quite alright on a tablet - it tries to be touch-friendly where it can without compromising mouse control, with things like finger-friendly panel controllers, widget drag handles and minimizing reliance on right-click in primary shell components. Re GPS, KDE has a wonderful mapping and routing (including follow mode) app called Marble with GPS support which also has a mobile version, Marble Touch. Re multitouch, I think there is actually some level of support, but I'm not sure. In any case, multitouch on X just recently got properly standardized with the merge of the official implemention in X upstream this month, and Qt 5 should support that when it lands next year, I believe. Run Linux apps: Of course you can run whatever apps you desire in Active.
