So far, Apple's forays into cloud based photo syncing have been a mess. Here's what we'll eventually end up with:
All photos sync to iCloud, where they live in their full resolution and quality. Any edits or changes to any photos will also sync into iCloud. If you decide to delete a photo, it will disappear across the board.
iOS devices will automatically remove full-size photo files once they've been uploaded to iCloud, then download an "optimized" version (more compressed, lower resolution) of the same photos that takes up very little space.
You won't need to upload and delete or pick and choose which photos are on your device. The optimized photos will be very small so you can just keep them all.
Sadly, this isn't going to work yet because iPhoto still exists on the Mac and it's still using Photostream. The entire app seems buggy as well. I'm sure it'll eventually work well, but until all the pieces are in place it seems a little strange to push it out.
