I really can't find the energy to be outraged by anything on your list.

The UI isn't amazing, but it gets the job done. And it has some neat features that I like, like play coins, the pedometer, street pass, the daily log, etc. And you can make folders. I really don't need anything but that. It does everything its supposed to do.

Downloading while playing, I guess I just don't care. You can set up the download and then when you're done playing, just close the system and it does the rest for you. That's totally fine with me.

eShop is kind of a pain to navigate, I agree. I basically just type in whatever I'm looking for in the search bar and do it that way. It could be better organized, with categories for demos and so on.

Account system would be nice, and I think they're moving towards that soon. They just unified billing and said they're not done yet.

Region lock is a big let down.

Battery life is fine for me, and its about comparable to Vita. It is a step down from DS, but I can live with it.

Ergonomics are fine for me.

Demos are fine. I've never even played one 3x. And most give you 30 tries.

You forgot to mention the biggest unique aspect of it, which is the glasses free 3D. Works great for me, and after I got used to it, I miss it when its gone. It definitely adds to Luigi's Mansion, ALBW, and 3D Land quite a bit.

And they're about to add MiiVerse soon, which I adore. And you can make posts offline and it sends them when you are at your next internet spot.

I'd give it a 7.5 / 10 based on just hardware and system UI features. The real wealth of the 3DS is the games. DS was the same. If it gets a fully functional MiiVerse, I'd have to rate the system all the way up to a 9 / 10. It's better than Xbox Live and PSN in many ways, with each game getting a dedicated forum.
