Ubuntu has already been touch-optimizing Unity for a long time. Ubuntu (actually the credit should go to Gnome and GTK for smooth scrolling, and Linux kernel for touch drivers) now perfectly supports smooth touch scrolling along with certain three-finger gestures to move windows around etc. They might even be ahead of Windows 8 in terms touch-compatibility. What they should do now is to convince more OEMs to ship Ubuntu devices.
