PNG is not really suitable for all image types, at least not for web
images. It is ideal for vector art, pictures of text, and anything else
with a limited number of colors or when transparency is needed. It is
not really suitable for photos or art work with a lot of gradient colors.

Actually, there is very good support for png alpha channel. IE is the
only "modern" browser that doesn't support it, at least not natively.

Not true. A photo in png will probably weight several times more than in
jpg format.
