Wrong: I rather leave it to professionals (my LBS) who know what they do, instead of relying on some crappy hobby project and risking broken equipment.This is like saying I don't want to change the oil in my car cuz one time they left the drain plug loose.
I have never had an issue with firmware updates, with 6 bikes over three years. Also a shrug.
I really don't get it - they put updates out to fix errors and compatibility, but people don't want them. If I ran my network like that we would be out of business.
