Subject: [Leica] perforations

Leica was the first to use perforated film so why doesn't Leica take the
lead and develop a camera transport system that uses full width 35mm film
without those useless holes and stone age sprockets?  

Pinch-rollers are quite adequate and can (for instance) position a magnetic
tape on a computor tape drive within microns.  Vacuum on the pressure
plate(head) and chrome guides ensures media flatness, so the "margin" is
not required.  The vacuum also gives excellent start/stop performance.

This would give over 20% extra film area for free.  With present lenses
there would be only a tiny amount of corner vignetting, if any.

I believe Leica was left out of the APS scam so why dont they hit back with
a meaningful advance.  I am sure that Leica could do it.  Star Wars 2.  
Flatten the opposition with precision engineering.  Or am I missing
something obvious here.
