exFAT, bleugh
Given my experience with exFat - formatting a device on Mac was unreadable on Windows, and vice versa - I avoid it at all costs. Not being able to read it on Linux was a bonus, a barrier stopping me from using this crap.
Add to that my Synology NAS wanting $3.99 for a driver (not an unreasonable amount) but needing me to create a login, add a payment card, etc, created another barrier for something that should be free anyway.
What the world needs is a free and open source, high performance, high reliability filesystem that can be used in embedded devices. It's not exFAT. Even the name makes me think of cooking by-products, disgusting.
