Very good tip!
However
I would like to add that my first mp3 player had 256MB storage. And now my phone has 256GB. 1000X
My first laptop had 512 mb ram. Now my phone has 12 GB ram. my computer has even more.
My first iPhone had 16GB of storage, now you can get a 2TB iPad. And iPhone start at 128GB? I am not sure as I don't use any apple devices anymore.
I'm trying to say that another option is just paying for more storage now. And later your 2TB worth of stuff will take only 5% of the total capacity of future mobile devices. And you get to keep master quality.
