All the SD cards I've seen have FAT filesystems on them.  The firmware 
in cameras almost certainly can't handle anything other than FAT.  
Android devices with SD slots probably expect FAT SD cards too, though 
they might be able to handle ext3.

FAT actually makes sense for removable storage in many situations, 
because everything can understand it and UIDs/GIDs don't make sense for 
things that can be attached to different devices.  I don't think it'll 
be possible to get rid of FAT for this reason.  (And isn't there 
something called ExFAT that SD-using devices that take cards > 32G are 
required to support?)
