Simple. I am a (very) active Linux kernel hacker, adding tons of new features to my (and others) Empeg (aka RioCar) player, and the extra 4MB of memory on a Mk2a may someday be useful to me. Also, at the firesale prices, I cannot pass up a chance for a larger harddrive that just happens to have a RioCar Mk2a attached to it for about C$200 extra.

Cheers
