This is not exactly the deal of the century, provided conditions do not change in the near future. The 9to5Mac team found that the 200GB iCloud tier costs $ 3 a month and Apple has been offering iCloud testing for 30 days. This would be more meaningful if Apple granted access for a longer period of time, much like Apple Music's six months for subscribers to Verizon's newer plans. It's safe to say that this will not swing you to an iPhone when the freebie is a deciding factor ̵
This does not look like the target here. Rather, Apple seems to use the iPhone upgrade cycle as an opportunity to boost its growing services. It is hoped that iPhone owners will find that only is an all-inclusively enough device (enough for most users) that they are willing to spend a little money every year to maintain this safety net. This will not satisfy the many people who wish that iCloud's free tiers would offer more than just 5GB of storage, but it's a validation that Apple needs to be more aggressive when competing with Google Drive or Dropbox.
