- Archaic download system. Can't download and play at the same time, either I'm stuck on the eShop or I have to close my console.
- Horrible account system, why are passwords for my CC between 4 and 8 characters? Please don't tell me nintendo stores them as plain text. Can't think of any other reason to limit password length.
- eShop is awful to navigate and to use.
- UI is horrible. Ugly and horribly inconsistent. How come I can't fully use the OS without the stylus? Why sometimes B takes me back but other times not? Why I can't use the home button sometims? What is the deal with the inconsistent buttons all over the place? etc.
- It's slow. Not dead slow but orders of magnitude slower than the competition.
- They try to squeeze every penny out of you! There's nothing free, they sell you clocks and notepads. Even demos have a limited number of uses.
- Multitasking is a joke.
- Region Lock.
- Hardware design is awful. The whole purpose of the clamshell design is pointless when the console doesn't close completely. The damn touch screen is a joke and requires you to use a protector since the stylus damages it way too easy. That damn volume slider is a terrible idea and it's too easy to hit by accident, buttons feel very cheap, etc.
- The ergonomics are terrible. The original GBA was the last decent console design by nintendo which felt right.
- Terrible battery life, probably the worst battery life out of any handheld out there.
I don't even want to talk about the stupid account system or the horrible, horrible screen. It has a worse screen than the PSP had in 2005. 3D games look so bad on a XL.
Any other new owner disappointed by it? iOS gaming lacks some decent input methods but it gets everything else so damn right.
