Filofax Pocket

The name 'Pocket' might be a bit of a stretch, but these organisers can fit in large pockets - great for a coat pocket or perhaps if you wear cargo trousers. Otherwise, they'll fit a bit more easily in most bags than the Personal size, without sacrificing too much writing space. Their increasing popularity means the Pocket now has almost as many choices for refills and accessories as the classic Personal size - and it's just that bit easier to carry.

Maybe people now are putting more emphasis on portability, or maybe it's just the reality that a lot of our information is going to be in our phones and computers, with the joy of using analog tools like these reserved for the things most important to us.
