The Photos app for OS X Yosemite.
Apple announced that they would make a Photos app for OS X Yosemite coming early next year. This is very similar to the iOS Photos app in design and app icon.
The thing I noticed in the demo is that the app is VERY similar to iPhoto when editing. Does that mean that iPhoto will be killed off soon? They can't keep an iPhoto app and a Photos app since it's way too redundant. If iPhoto gets killed off, what about the rest of the iLife apps (iMovie, Garageband)? Will Apple also kill off iPhoto for iOS as well?
