I got the S90 and the Ike housing... partially because of size.. part because of cost, and part because of 67 mm "options".
If one wants to spend the money on the Fix housing, consider the new Oly micro 4/s dslr...with the same 67mm attachment. Or the 10bar and the new panasonic.
The fix and the G90 is getting very close to the price of the oly with housing...boy that is an interesting choice.
While I suspect I am headed for the Panasonic and 10Bar, for right now the S90, with wideangle and macro is a very nice package....one I am glad I have.
I am very excited about the coming wave of Micro 4:3 and Canon and Nikon EVILs but I don't think the new ELP-1 is quite there for me yet. It has manual controls via buttons where as the S90 has rotary knobs and direct access (with the FIX) and that is worth a lot to me. But, you and me both, that new ELP-1 could offer some very interesting options if the housings come for it and it's brethren yet unborn. The Oly housing is just to big, I see no need for the view finder when you have a giant LCD, it just makes the housing big. It is possible some of these will with one port take wet lenses and with another port dry lenses, could happen .
