Thread Starter, did the camera you use come with any software.
I use a crappy older Cannon Powershot A520.
It came with a pretty good batch of software, and the recent free updates from the cannon website make it all universal binary, so it now is very fast on my mid 2007 iMac.
Their latest version of "ImageBrowser" is quite nice, I personally like it better than iPhoto. It does not take your photos hostage. (a loaded statement, here come the fanboy attacks).
This line of cannon software cannot be purchased by itself, but if you go out and buy their cheapest camera, you get it all for free. Or, do you know anybody with a cannon digital camera (I think we all do)?
ImageBrowser even now comes with basic .avi manipulation abilities, for those little movies one can make with their point and shoot digital cameras.
I really do not get the itunes/iphoto comparisons. I am under the belief that people tend to want to "do" far more things with their photos than with their music: I only listen to songs, I can think of about a dozen things i want to do with a photo. Maybe that is just me, coming form a graphic artist background.
Also, I have used Mac's exclusively my entire life, since 1987. I do not even know how to use Window OS, seriously. so the whole "window's-habits" thing does not apply to me.
I am not an iphoto hater, I am just not a lover of it. Cannon's ImageBrowser does all i need it to.
