OK, so it's an adapter that's designed to be flush wit the case. I get it. For some this could be of value.

From a design standpoint, I would have been far more impressed had they taken the time to engineer a removal approach that does not require a special tool. The first thing it's going to happen is that you'll be on a trip or out of the office without the "key". There are tons of ways to make tool-less removal possible. This device is very simple as it has no real circuitry inside. It's an exercise in mechanical design, and they chose to not go the extra step and give it tool-less removal.

On my W520, SD cards go in all the way and then pop out when you push them in further (spring-loaded). Something like that could be built into this card itself pretty trivially. Added complexity increases costs a decent bit for something like this, though, I'd imagine.

That's the beauty of designing with plastics. Sometimes you can add significant functional complexity to a design without a corresponding increase in cost. The mold costs are not correlated to functional complexity. Adding the "push to remove" function could, depending on design, cost exactly zero both in terms of mold costs and materials cost.

The same is the case for a number of other options.
