Offset is the angle the projector lens aims when the body is mounted flat. A low offset will have the PJ shooting with the bottom (or top) of the picture inline with the lens, i.e. straight across. That is good for a low ceiling or a standard coffee table mounting.
A high offset will cause more of a shift down (for a ceiling mount). That shift in inches increases drastically as the projector is moved further back, which is often done to increase the size of the picture. You can try to accomidate a high offset by tilting the projector, but the more you tilt the greater the keystone.
I've heard the InFocus changed the offset on their projectors because "high end" rooms often have a 10 foot ceiling versus a standard 8 foot ceiling.
The net of it is based on all that geometry, a 4805 worked really well in my room and an X10 just won't.
