I do, I notice it, the card slot. Exposed is defined as: to make visible, therefore yes it is exposed because I can see it, the slot and the mini-SD inside. As I've said before, it is personal perference, some people just like side-loading better than front-loading when it comes to removeable media based flashcart.
Not spending a long time with the interface does not justify not having a skinning support. Afterall, you will see the interface everytime you turn on your NDS with SuperCard to play a game. Once again, it is personal perference, some people think it's not important, but some do. The most you can do is tell them that the skinning support is not there, and it's a con, rather than covering it up with your personal opinion such as 'oh you only see it for 5 sec so it doesn't matter'.
