Similiarly, I have removed all related netbook, such unity, mutter, etc. and returned back to normal desktop session for the UNITY is really SLOW.

Indeed, I am also dislike netbook-launcher, a traditional gnome menu applet is far more better.

Maximus is great and the only one real important thing for small screen.

So, Main Menu + Show Desktop + window-picker-applet + Notification Area + Indictor Applet + Clock is all one needed. all these applets are placed at the top panel.

In this way, I changed ubuntu-netbook-edition to ubuntu-desktop-edition with a classical UNR-like interface.
