Dropbox's sole 1TB plan costs $0.12 per GB per year.
Google Drive costs $0.24 per GB per year for 100GB plan and $0.12 per GB per year for 1TB to 30TB plans.
Apple's iCloud costs whopping $0.59 per GB per year for 20GB plan and $0.24 per GB per year for 200-1TB plan.
Apple does not necessarily have to become cheapest, but I would like to see some pricing innovation, such as flat $9.99 per year for each 64GB increment ($0.16 per GB per year) consumed beyond free storage, with ability to share storage with family members.
Yes, this. I'd also like to see the return of iDisk features..or what DropBox/Drive do now with file sharing, etc. I never really understood why Apple took this away as they were ahead of the game on it. I'd be all over it again if it came back.
But as it stands, my library of mostly raw files is huge and the cost is not worth it for just photos if you have an existing backup plan. I send what I need to PhotoStream when I need it.
