Count me among them. I'm moving my SliMP3 downstairs as soon as I get
around to pulling some Cat5 (or buying some 802.11b stuff). It'll be
right next to the TV, so I'm glad I have the fix done beforehand, but
I've never noticed anything.

Was the RF interference really nasty before the fix, or just a problem
if the player was very close to the TV reciever?

... or on the cement floor, or behind the desk, or underneath the
soldering iron for an extended period - I mean 5 minutes, not 10
seconds. ("What smells like burnt plastic?" :-)

Or in case you discover another important cap is missing (unlikely but
possible) - I've noticed a lot of unpopulated pads. Some of the bigger
ones I saw:
	The DAC layout has pads for a 14-pin chip, and most of the empty ones
have traces on them (in one case, all the way to the PIC) - possibility
of a different DAC?
	There's an empty set of holes (J7) above the IR reciever - is that for
the pick & place machine? They don't have traces.
	Not a pad, but the word "Halloween" is printed on the copper layer,
just below "www.slimdevices.com".

	What are those for?
