Think Tank is a company who listens to their clients and it shows. The people asked for a new color and a slot for an iPad and the people got just that. In May, the Think Tank Retrospective 7 bag will be released with these new features. The new portable slot will be able to hold either an iPad or a 11″ Macbook Air. It also appears that their entire Retrospective line will now be offered in the Blue Slate color as well.
In a couple weeks you will be able to order the bag soon from their website here. In the meantime you can have them notify you when its ready to ship.
