Honestly, I'm more interested in reliability and mechanisms to prevent data loss...
Last I checked, the exFAT implementation that MS released to the public was missing some key features that made the Linux port less reliable, particularly for removable storage devices (making it not much better than old school FAT). Has that been fixed already?

This is the result currently (last 7 days):
If we exclude Android and iOS (which make for 29.6 + 15.9 = 45.5%), then the contribution of each of the others would increase (by 100/45.5 = 2.19), leading to 11.388% (5.2 * 2.19).
