Only after reading your comment I understood that it does not have a spring loaded slot, it's the first that I know of that does not have one. And now I'm wondering if there is not 1cm more to make the card go fully inside the computer? Doesn't look too hard (but maybe it is?).
The more I think about it the more I agree the real design flaw is from Apple.
As I see it, there are only two reasons why the SD card doesn't go all the way in in an Apple laptop:
* So nothing can get stuck inside.
* So valuable space isn't used up inside the computer. The motherboard in a macbook air is tiny. The extra half-height of the SD card that would be necessary for it to go all the way in is significant.
Either way, as it stands Apple hasn't provided a spring-loaded mechanism, so they have to do something like this. They only made the removal tool by popular demand: in the Kickstarter they were just advising use of a paperclip, which seemed reasonable. Over-engineering is always a danger, especially when you're fighting to just get a product shipped.
