Are apple products overpriced with shitty build quality as well?
Yes.
The failure to fix the joycon reminds me a lot of the butterfly keyboard Apple did. And the time they took to fix it as well.
And similarly, it wasn't always like that.
They're very similar companies when it comes to some philosophies of not listening to costumers, deliberately keeping features out and so on.
As for Nintendo influencing Apple directly, I can't think of a time that they did; but again, given their philosophies, they always overlapped a bit, the closest I can think of is Gameboy Special Edition (1995) and Gameboy pocket (1996) having clear colors that preceded the iMac/iBook range for a few years.
Then again, Sega Saturn also had clear versions, so I don't think it was a direct inspiration by any means.
As for the DS and the touch screen, I don't think it has any relation with the iPhone (specially seing we're talking capacitive vs multi-touch), BUT, both the iPhone and the Wii were on the same page in regards to what they wanted to do with their interface at first. Both wanted apps to behave like channels (and this was before app stores launched), same wavelenght. Their home screen ethos was the same and the Wii actually released first.
Different results though, the Wii was sluggish and never quite delivered their vision. But then again they don't release new hardware every year, iPhone 1 didn't deliver much either, but it was a better proof of concept still.
