Fair enough. One has to wonder why there's still a mirror in there. :-)

My Sony lets the light hit the sensor, then puts the display in the 
eyepiece. You don't have to screw around with a whole bunch of internal 
mechanics, waiting for the mirror to get out of the way, trying to draw 
fancy stuff on the viewfinder without having to do things screwy. :-) No 
left-overs from mechanical days. Plus, you can do IR.

I'm still not sure how the thing autofocuses without interrupting the light. 
I can only guess it's using a half-silvered mirror, and hence the 
prohibition against linear polarizers.
