Very true.  Armel does indeed run fine.  However, for certain applications
having an armhf port such as Raspbian will make a big difference.  One
example is the Robot Operating System (ROS) by Willow Garage which is
actively being ported to the Raspbian at this time.  It includes a number
of physics libraries and applications that process complex sensor data that
will benefit greatly from a hardware floating point unit and the more
efficient armhf ABI.  The interesting thing is Willow Garage is choosing to
initially port to Raspbian armhf rather Debian armhf because of the
ubiquity and low cost of the Raspberry Pi.  Also, the knowledge that the
packages will run perfect fine on Debian armhf if someone chooses to do so.
