There is also the legal implications of it.
Again, I'll bring up an article I posted years ago in PRSI:
Could government agents really get access to all your private data in less than a minute? Experts say no but warn we are moving in that direction.

The issue here regarding local storage versus having some SaaS holding your data is the implications of search and seizure in the US. If you are in control of your data (read: local storage), the authorities would require a warrant to get to seize your devices and search through them (as they should).
However, with going to any online storage (whether a service they offer, Dropbox, etc.), the companies running or hosting that online storage for you are 3rd party to any investigation you may be under. And as such, no warrant is needed; in fact, only a subpoena is needed. And making that even worse: any clerk of the court can write up their own subpoena and have a judge sign off on it. The problem with that: every single lawyer here in the US is a Clerk of the Court. They could write up their own subpoena, file it, and if the judge signs off on it, can subpoena that 3rd party for your data, and you would not be aware that they did, because by law, that Clerk of the Court would not need to notify you of that subpoena; you would be 3rd party to that subpoena.
So by going with that subscription and having the SaaS hold your data, you essentially may be indirectly waiving your 4A right against search and seizure. I'd rather not take such a risk for the sake of new features.
