(the FR uSD card slot is quite difficult to access and if
USB 1.1/WLAN/Bluetooth is not too slow many people
might prefer to leave the uSD card there most time...)

What about the support for owners/groups, (symbolic/hard) links and device files?

And the Linux vfat seems to have problems with filenames containing colons,
see http://lists.kde.org/?l=kdepim-users&m=123210608518115&w=2
where someone did a "Backup" copy of his maildir files to vfat and didn't notice
that the destination directories where emty...

For me vfat was therefore always a makeshift/stopgap/... for a data exchange
with the Windows etc world, but not a competitive Linux alternative and not
"most recommended".

Good night
