Enough space for 8 physical games, 2 extra mem cards, and is a solid case that can take some abuse. I don't travel much anymore but I do not fear my vita getting damaged with that case.
I have that case. Dropped it in a parking garage, on to cement, from waist height (I'm 5'11"/ 180cm). It sprang open on impact and ejected my Vita about 3 feet away. Nothing too serious, just dents on the triggers and a few on the metal edge frame (screen was unharmed, phew!). Anyways, it's anecdotal, but caveat emptor. It's great as far as storage and protection from casual damage while you're Vita sits at home. Just don't drop it.
I have this nyko power armor case the "power" part is misleading its just a metal shell with foam lining. The lid is spring loaded, so you press the button on the bottom and it flips open. The rear touch panel is inaccessible and its not really comfortable to hit the triggers while its in there. It's not secured inside in any way so you can just pull it out quickly. Honestly though, I've never taken the vita out of my house.
I have the same case. It's fantastic in that it's hard, has stick cutouts and is ultra low profile.
It's barely bigger than the Vita so I can keep it in my pocket. It probably won't protect from a drop of more than a few feet but it's still the best thing I've tried.
