Yeah, it does (put you in the want category).I have to admit storage management annoys me, I like to do it between phones, not as I'm going along - I guess that puts me in the want category for plenty of storage? I can plug it in and back it up, but I don't like having to take stuff off to keep space free.
What you said is one of the reasons I want the max when I buy. I never need to worry about storage or any of the OS issues that can come with not having enough.
It's also nice to be able to use that storage for things when I do actually have a need for it. For me, nothing sucks more than needing space for something and not having it.
