FWIW, I've never had both magnetos fail or even complete failure of one magneto 
in 29 years of aviation (which is not to say that it doesn't happen, 'cause it 
clearly does).  But I have had electronic ignition systems fail, including my 
80s vintage motorcycle.  

Nothing wrong with flying electronic ignition if it's done properly.  I've seen 
lots that are done right, and I have flown some of them.  I've also seen a few 
that I wouldn't go near.  For the most part, what I've seen done by the KR 
builders on the Corvairs and VWs appears to be well thought out and has good 
redundancy provided that there is sufficient battery behind it to provide 
enough power in case of electrical failure.

As experimental aircraft builders, especially in the USA, we are allowed to 
build planes for the most part how we see fit.  However, the certification 
process is there for many more reasons than to dig $$ out of your pockets to 
propagate the use of antiques.  

The FAA does not require the use of magnetos in certified aircraft.  For 
certification purposes, it does require that if the ignition system is 
dependant on battery for power that there be a minimum of 30 minute reserve 
with part of that time under a normal electrical load.  So why is it that 
Cessna and Piper are still using magneto fired engines?  OK, Cirrus is a new 
company doing cutting edge work even using electronic FADEC controls and glass 
cockpits.  So why are their engines magneto fired as well?  Think about it.  
I'm sure their engineers have.
