No I didn't, but I have a macbook air, iMac, iPad and iPhone, so I know enough to manage resources and not carry every damn file with me all the time on all my devices.
That's still a personal choice not an indication of any form of knowledge.
I have a large library of music. I want immediate access to not only music I listen to often, but music I've just obtained very recently from either iTunes or soundcloud etc... and music I know I'll want to listen to. I don't want to have to sync my iPhone daily just to decide what to remove and what to keep. I want the bulk of what I know I want to listen to from my collection with me and even when I delete a few albums or a DJ Set that I haven't played in a few months', you can almost guarantee a conversation about the artist will happen and I'll reach for my iPhone only for the track to still be on my Mac because I've removed it to make room for something else.
My Mac is a pretty good example of what I mean.
I have an SSD in an optibay. It's only 60Gb but it only needs to contain the OS and any files I use regularly that take quite a lot of time to load off a conventional hard drive because of the number of small files or sustained readspeed of large ones. I also have the Mac Mini's original 320Gb drive with my iTunes Music library on it and general document, 11Gb of which I can fit on my iPhone at any given time and then a 750Gb drive externally with larger media files on like TV Shows and films.
All of this available from my Mac at the same time. I don't need to wait till I'm somewhere else, plug my Mac into a drive there and then get to the file I want, it's all there on my Mac, it's just not all in it's internal storage.
