If you run the "mount" command, you'll notice that frequently used /tmp
and /var/run directories are actually in tmpfs i.e. in RAM (which size
is limited to 1/2MB, anything needing more space should use $TMPDIR i.e.
/var/tmp).

Having directories required in device bootup on a media that user
can remove (and which isn't inserted in the device when user gets
it out of the package) is not really a good idea for a consumer device.

JFFS2 is for raw flash, not memory cards. Ext2/3 aren't recognized by
Windows or Mac so most(?) users wouldn't be able to copy their media
files on them. The cards are formatted as FAT when people buy them.
