Not at all. I consider the points you've stated minor gripes at worst. Maybe my expectations are more moderate but I consider it as a device for playing games and nothing more. The eShop and UI all do their job adequately, everything can be accessed with ease. Multitasking works fine as long as you consider it a supplement to its primary function, playing games. No complaints on the 3DS XL design front, the original 3DS however does has a well documented screen scratching problem.

As for ergonomics, it can only be judged on a personal basis but I have no gripes there either. Battery life is good enough, I'm on the road more than four hours everyday and due to smart power management I've not even once ran out of juice. The one point I must hand to you is region locking, it's very unfortunate.

Actually, my only gripe at the time I bought it were the lack of games, a problem which has since been resolved to the point I've actually built up quite a backlog.
