I think far too much emphasis is being placed on the amount of wood being removed etc because like I said before, the bridge is designed to compensate for these changes.

Every change to any bridge affects tone and sustain. We have gone to great lengths to use good tonal materials such as steel to get a tone that we think is great. Strings attached to springs resonate only 75%-80% as long and usually have a softer attack because some of the resonant energy bleeds into the springs. To compensate, we developed spring buffers and dampers, a great saddle design, and lots of steel.
As a result, EverTune’s attack and sustain are as good and better than other floating bridges, and the tone is louder and brighter than a stock bridge on many of the prototype guitars we have installed. Many people are concerned that EverTune’s functionality will be at the expense of tone. To this we can offer that the huge majority of our beta testers say that their guitars sound MUCH BETTER after the EverTune installation. This may be because guitars that are beautifully in tune all the way up the neck, re-enforce the sounds and frequencies of chords and melodies. It may be because of our high quality steel saddles. We feel that the tone of this first ever EverTune is awesome, and we are constantly working to make it better.
I personally think it's one of the most interesting and genuine advances in guitar tech in recent years and I love the fact that it's purely mechanical and isn't using a computer to do the work, and I own a Line 6 Variax acoustic and I'm about ready to get a Tyler Variax soon too.
It has a fundamental purpose - to keep your guitar perfectly in tune - and it works!
Not sure if I have the technical skill to be able to install one myself, but I am definitely going to look into getting one fitted to a PRS SE in the not too distant future.
