I'm a data hog. Storage is cheap and it should be available on my phone also.
People always saying physical Media is important, and most of the time they tink of cds and dvds.
I use my sd cards for physical Media sorage.
I used my camera and accidentally recorded 40 gigs of video.
With external card I do not have to worry.
Music, books, picture heavy pdfs, movies full tv series sits comfortably in my palm.
