Does this replace the D40x? Makes sense so you can share lenses - Benjamin Golub

Yep, I returned the S90 b/c I wasn't that happy w/ it, and sold the Nikon D40. I decided to go Canon whole-hog. - Ana

What didn't you like about the s90? - Benjamin Golub

I just didn't find the low-light quality that compelling. Seemed like my little Powershot is good enough when I need something compact. - Ana

I think I'm coming to the same conclusion, Ana. Situations where there's not enough light for my SD780 and I don't have my DSLR seems like a corner case that doesn't warrant the expense (and to a lesser extent extra bulk) of the S90. - Ken Sheppardson
