But can you set DPI independenty for the two monitors?  I'm guessing
not, since you mention the "weird look of windows" -- that's probably
due to use of the wrong DPI on one of the monitors.  With multiple
screens, you _can_ set DPI correctly for two different monitors.

Except for the "moving windows back and forth" it works the same with
dual screens except you can properly set DPI for both of them.

There is one other disadvantage of having multiple screens that I
forgot to mention.  Apart from the gtk-3 selection brokenness, there
are some buggy X apps which just plain refuse to run on multiple
screens simultaneously (Firefix is one).  They were apparently written
by MS-Windows programmers based on the assumption that a computer is
always used by exactly one person to run exactly one program on
exactly on screen.  Most other X apps are properly written and support
multiple screens just fine.
