DrCookies,
I've been a Mac user for almost 20 years now, while my husband is a PC guy. On the plus side for Macs, they generally last longer, have fewer problems, and are better integrated for ease of use. On the negative side, if they do fail, they usually do so quite spectacularly and completely, at least they have in my experience.
iPhoto is a fairly simple to use program for importing photos from your camera, organizing them into albums, and doing some editing. I don't have the most up-to-date version (my iMac is currently going on 5 years old but still working well, knock on wood), but the version I have has a nice and easy red-eye correction, brightness/contrast, an auto-enhance that works so-so, crop, rotate, and a simple retouch brush. It also has convert to b&w and sepia. My version also doesn't import any video shot on the camera, which is annoying to have to go to another program to save those.
I took a look at Apple's site to see the most recent version, and it looks like they have added significantly more features to the program, especially in the editing capabilities. (hmmm.... Dear Santa, I've been very good this year.....)
