Lawdog,
This subject has been beat to death, but to answer your question. So far I like my "good old reliable" electronic switch. It sure has had a workout this winter in the Northeast and has given me no problems. I doubt that anyone could argue it's convenience. As far as durability goes, no one knows the answer to that. The lever engagement "ain't like it used to be" either. I expect the lever will die a slow death like the locking hubs (ever had the pleasure of engaging those beauties with a pair of channies with the snow blowing up your "nose"?). Personally, I don't miss either of those features.
