Same goes for me, too.

If the answers to Russell's questions (which I deleted) are positive
I think this is a good idea. It raises the base price of the board,
but a board with _no_ memory is worthless anyway. For me,
personally, 32 MegaBytes in surface mount and no SIMMS would be OK,
but I realize that the amount of memory people want, and want to pay
for, varies wildly. Russell's compromise addresses that.
I guess the real key is whether Waldorf can put surface mount
components on both sides of the board. There is probably very
little difference between SIMM sockets and surface mount if it's all
on one side of the board.
