I should be getting my WF next week, YES!! I've been contemplating a Brain Cell for my 15" MacBook Pro. Once it's clipped into the WF, is there any additional space for a few articles of clothes, folders, etc.? Not sure how much space is taken up by the Brain Cell.
On the other hand, I already have a vertical cache for my Synapse 25. I can always toss that in the WF, of course it won't be secured because it doesn't have annex clips. Thanks for any help!
