Why are our piston aircraft still flying around with 40-year-old tractor mags and a fistful of engine controls, instead of modern digital single-lever systems?

Now, both TCM and Lycoming are readying their own digital engine control systems slated to appear in a year or two. Here's an update on TCM's Aerosance and Lycoming/Unison's EPiC from the staff of Aviation Consumer.
