The new Ubuntu 12.04 Precise Pangolin comes out tomorrow.  I happened 
across this article...

...but maybe someone here can suggest a better one.

I wonder why Unity is a big issue -- can't we install whatever we want and 
us it?  For example, KDE or Gnome - just choose one at login?  I used to 
do that in Solaris about 12 years ago and it wasn't too big of a deal. 
Isn't it easy to do that with Ubuntu, too?
