How much stuff can the Imago hold besides the Brain Cell?
I'm looking at getting a messanger bag which I will probably *not* put my laptop in much of the time, but which I do want to put my laptop in sometimes. The Imago looks like a cute little bag.
I've got the size 5 Brain Cell for my laptop already (and really love it). I'm wondering -- once you've put the Brain Cell in the Imago, is there any room left over for other things (a notebook, a bottle of water, whatever sock I happen to be knitting at the time)? Or does the Brain Cell pretty much take up all the available space?
