I'm afraid it's the best I found yet on Linux. It may depend on the version you use (I've tried the one for Ubuntu 14.04)

Yep, I guess W8 was conceived for touchscreens - which probably explains why people seem not to like it on not-touch screens...

I don't know how powerful is your machine, but on mine Gnome 3 is just useless: slow and tiny scren fonts and touch surfaces.

It does provide an on-screen keyboard, but just as with Unity the way it appears and disappears is a mystery to me.

What's more, the Unity and Gnome devs (I don't know for KDE 4) have found intelligent to set the entry point for their windows in some "search" field (apparently the "modern" way to look for applications). The result is that the keyboard pops up, although you'd actually like to sweep with your fingers...

I've seen someting about a tool called "Touchegg". Seems to rely on QT4 but be relatively UI-independant. Multi-fingers gestures seem possible. I'll take a look.

This is a very profound philosophical truth :))

I haven't yet had time to watch but here a Peter Larsen seems to have take a large tour of Linux's touchscreen possibilities:
