I'm mainly concerned with my photos and videos. Is have google drive for docs and use my free iCloud quota for mac stuff. I'm confused how iCloud photo library works. I know it's pretty redundant at the moment until OS X app for it is released. Once that is available it will be very useful as it keeps edits synced across all devices right? Does it store everything off the device so no space is take up? What about camera roll photos and videos they will still be on your iPhone right? But the iPad or Mac just sees them as in the cloud but not taking up space? How does Dropbox compare? It can sync all photos and videos right? It works right now across all devices. But what are the downsides? Can i still easily grab videos to edit between iOS devices for example, what about Mac integration. Is iCloud library once available more seamless or doesn't it matter?
