I got the Aus model too matzesu, I think you'll like it
I've been enjoying it, got some nice little games on it, and those Korg apps are both on 50% sale at moment [think it was 50% anyway], so I picked them both up.
Also the old classics in 3D from the eshop are great, like Shinobi and Space Harrier, if you like those games, they look great with the 3D effect I think.
Not had much use of that little nub analogue yet myself, but the shoulder buttons are decent, the positioning of them is fine for me, so don't see any problems with the similar style used on Pyra.
Definitely a decent little console though.
Opening the back case to access the MicroSD is a bit lame though, not sure if it's mine only or by design, but the screws don't actually remove completely, you just loosen them then crack open the cover... seems a bit fragile and almost as if it's going to crack just where the screws are, right close the edge
