Xinerama (or the proprietary equiv.) is usually preferred today anyway.  With 
multiple sessions, you are unable to move a window from one monitor to the 
others, and most people expect to be able to do this.  If for no other reason, 
because this is the way OS X and MS Windows handle multiple screens that are 
not in clone mode.

Xinerama does have its disadvantages.  The first I can think of is incorrect 
DPI reporting when the two monitors differ in DPI.

I use a two-head Xinerama setup for my desktop machine.  It mostly works, 
although doing anything involving activities has the potential to mess it up.  
The fact that my monitors have different DPIs and aspect ratios also results 
in some quirks that are trivial to work around.
