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.
