But yeah, I agree, whenever a large Japanese company that is not Nintendo does software (at least for consumers), you can pretty much expect a disaster.
(I know there's a small group of startups that do good stuff - I am not talking about them.)
I mean, which other large american hardware-centric companies have managed the transition to software well?
I haven't used a PlayStation in a long time so I don't know the current state, and I would guess Nest is not helping the US side of the equation. Apple isn't exactly covering itself in glory in the last couple of iOS releases (never mind the "California" series of OS X releases).
The PS4 has a weird UI that feels oddly half-finished, but does okay on system level performance. It's sort of where the Xbox 360 was in 2005.
Obviously I'm biased, but I agree Nintendo is the only major Japanese company that has any idea how to write software. They also have a legacy of incredibly talented programmers that they respect more than most Japanese companies.
