The whole point of iCloud backups is to be easy enough for anyone and everyone to use them. They’re supposed to just work. However, Apple only provides 5GB of storage space for free. Granted, Apple doesn’t count some things, like apps, iTunes media, and Photo Stream against that storage allotment, but 5GB is still far below most peoples’ needs, and far less than what Apple’s competitors have recently been offering. What’s worse, even if you’re willing to pay extra the highest you can go is $100 for 50GB. That’s despite Apple selling devices that hold 16, 32, 64, and even 128GB of data. You literally cannot even pay to get enough storage to back up a single device much less multiple devices.
Even if Apple wasn’t able to provide free iCloud backups for every iOS device they sell — and I think that would be a huge boon — they should at least offer enough space for backups of 64 and 128 GB devices.
