I guess they only sell the device in Western Europe, or something.

Well, the technical people probably said, "Does this device conform to
the USB Mass Storage specifications? It does? OK, tell Marketing they
can put 'Supported under Linux 2.4.n or higher' in."

A portable storage device should be in a lowest-common-denominator
format, so that every computer you plug it into can read it. That means
(predictably) FAT16, since it's highly probable you'll find a Lose98
machine that you'd like to use this memory stick on. ext2 creates a
certain number of inodes when you mke2fs; the blocks used for inodes
can't be used for anything else, unlike FAT. 5% of space on an ext2
filesystem is reserved for uid 0 by default; "man tune2fs" etcetera to
reduce this percentage and get some more space back. HTH,
