I could care less about system features and UI design honestly. The ergonomics are a tad bit annoying especially on the regular 3DS but the XL and 2DS have fixed that issue for me.

To me personally, its all about the games and that is undeniable. I don't care about the lack of a proper account system, UI navigation, system capabilities, etc. because the 3DS provided some fantastic games. Everything else is secondary as it should be on a gaming console.
