Keynote vs ProShow Gold

Hi All,
I need your help. In the PC world I use a program called ProShow Gold and really like it. I am thinking of buying Keynote and was wondering if anyone is knowable about both programs. I would like to know if Keynote can do all that P/S Gold can do.
The things that are important to me are:
Zoom in or out
Pan
Set duration (Imovie limits the duration) of each slide and transition
Set length of any music track with fade in and out
Save the file so PC users can view the show and make it small enough to be able to e-mail it
I am probably asking a lot, but these are things I can do in P/S Gold.
Any help or input will be greatly appreciated.

Thanks,
Al

Al,
I am a recent "switcher" and used ProShow Gold on PC. I have Keynote but it's a Slide Presentation program--like MS PowerPoint. You might want to take a look at "Photo to Movie" at this link. You could always install Windows on the Mac to use your PC programs. I'm trying to steer clear of doing that myself.
