I think the TB model is about the worst of those TSA laptop bag designs. I've said that already on OBOW when they featured it. The clip thing is good for unclipping but is a pain for clipping it back together. You will need both hands and a support for the bag. Plus the computer is in between the two other sides of the bag which means you have to unfold the whole shebang when you want to actually take it out. What were they thinking?

The usual zippered clam shell design is already a hassle but this design tops it.

Really the only advantage I see to these bags is that you are less likely to leave your laptop behind accidentally.

Taking a sleeve out of a zippered compartment and putting it back in can be accomplished with a single hand easily. That alone should tell us about which method has the superior ergonomics.

For s super lightweight and inconspicuous laptop sleeve that passes as TSA pouch, try a padded poly envelope. It's what I use mostly. Protects against shocks and moisture, doesn't look like a computer sleeve (no attention from thieves), can be written on, saves space and weight in your bag, is easily replaceable and has a secondary use if needed. It also holds up very well.
