I hate touchscreens. They don't really work nicely, they're more pricey and I also hate fingerprints on a screen. Anyway, having support for that might not be bad, what is bad, if suddenly KDE folks go crazy (like certain FF devs who though version numbering is obsolete and nobody needs/wants version numbers, or like Apple inventing the one button mouse, cheers!) and think the world is one single touchscreen.
The other thing that caused a nervous reaction was "search driven". When I want to search, then I do a search. But when I want a classic directory (over)view then the damn file manager better gives me exactly that. Showing all the details I specify (name, date, size, owner maybe). KDE people messed up already with their damn semantic desktop and their file indexing etc. which just causes nausea for the user, software to bloat and systems to slow down. The problem is these things become less optional.
Stop TCPA, stupid software patents and corrupt politicians!
