@Q1712:
I haven't used Fireworks much at all, but I thought Fireworks was a vector graphics based application, where as photoshop was a bitmap based application?
Freehend is the vector based app from Macromedia. Fireworks is 100% pixel/bitmap based (it's native format is PNG [with some more data at the end]).
it just had good support for verctors/shapes very early (lot of them were integrated in photoshop later)
And it always was focused on Web (e.g. the whole thing u get when u use "export for web" in photoshop is exactly copied from the standard Fireworks interface, same with slices).
That are as well the main reasons why i used Fireworks instead of Photoshop, and because i never got used to the Macintosh feeling in the earlier Windows versions of Photoshop.
But i'm not using it anymore

P.S.: i'm not really sad. cause i'm useing a much better operating system now, witch only lacks a decent editor.
