Let me quote it in the exact words of the developer himself...
"The goal is to Create a desirable user experience encompassing a spectrum of devices... we want to create something, people want, and people want to use. It means we are less technology-focused, but are taken a user-centered approach..."It's very new actually, so currently I think it can be run in 3-5 specific Tablets... but that will/may change in the future. Anyhow, Plasma Active is basically another shell environment in which you can create a different application GUI's which are, again, optimized for Tablet PCs like devices.
|Well, that's the idea...|
In general Plasma Active runs on top of the KDE's plasma (obviously) and uses the OpenSuse 11.04. But again, PA can easily be ported into other GNU/Linux distributions as well. Few hours ago, Sebastian announced (one of the main contributors) few other new "invented" features for the PA project such as amazing virtual keyboard, activity switcher, etc.
|The new, virtual-keyboard...|
|The "activity switcher"...|
Have a look at the below video to get a better idea ("feat" Sebastian Kügler :P)...
