Hi, what about re-organizing applications,data,media,whatever.. into groups (tasks) and develop a new kind of desktop. A user would not have to go through Kmenu->Multimedia->Movie Player but he would simply choose "Watch movie", "Check email", "Browse internet", "Read news", etc.
The list of displayed tasks should be done in some intelligent way (like most common for that particular user at given time,..).
The selection would not only ask another question like "what movie?" and start some application(s) but should also provide a easy way to reach any kind of data related to that task.
For example: I'm coding some stuff in php, so the desktop would provide me kate with pre-opened files, access to ONLY related emails, access to other ONLY related data (images, pdfs, calendar events), access to php.net - all this handy organized in some kind of task related objects viewer (and all this in 2 steps of easy questions like "what do you want to do?" and "please select project").
If I'd choose "Watch TV", it'd open tvtime and todays tv schedules (and tell me that "You've missed the StarTrek at 16:30 again!"
)
Of course this should include a simple way to define tasks and assign objects to it (e.g. apps, email folders, files, ..) - maybe with right click->assign to task->...
