iPhoto is one of the reasons that I used to recommend Macs to my friends and family. It was the first easy, quick, and clean solution for consumers to manage and edit digital photos. Over the years it started getting really slow and problematic so Apple finally decided to give it the ax-and I couldn't be happier.

Great preview of Photos preview for OSX Yosemite 10,10,3. Looks like a great upgrade to iPhoto, (and a big downgrade to the functionality of Aperture).
