That 30 uses only is a bit of a downer, but realistically I wouldn't play the games that many times, even when I count 3 people using the 3DS.
It's not so much the navigation, but when downloading something it basically asks you 2 times if you want to download it. It's not necessary, it's also not necessary to ask if you want to download now or in standby mode, it should be done automatically. Not to mention the loading in between. If we leave the clicking but it's done instantly, it wouldn't be half as annoying.
