Did it look equally easy to open from the outside?... ...The tent looks a little slack, but the window/zipper/storage pouch details look very nice.
I'm guessing here, but no, the Tacoma Habitat did not look as easy to open from the outside. Releasing the latches at the front led to a lift of several inches (from the gas struts if I recall correctly how they're mounted). It still needs levering over center to deploy. It might be OK for me as a really tall guy, but even then it would be lifting from only one side and twisting the top as it was raised to flip it open. Perhaps Martyn or Mario will come in with better information.
(As an aside -- and not trying to argue at all -- but isn't the point of opening it to get inside the shell?)
Yes, the tent probably does look a little slack. The tent wasn't pulled into place at all after flipping it open. I'm sure the fit woulda been tighter had it been. Martyn noted that Nemo would be making a few changes to the pattern for the production models, one of the changes being to increase the coverage of the perimeter flap. The fittings on the inside looked nice in person, too.
