I'd consider Philips one (specifically whatever part of the company does Hue products; even with their recent base-station changes to only work with their bulbs). I don't think their base station has EVER crashed on me, not once. They made sound architectural decisions for the product as a whole - it's not some bloated Linux thing but it runs FreeRTOS and does only what it needs to. I have one of their push-button kinetic power light switches in my setup and I've forgotten that it isn't an old-school lighting setup most of the time. That's because of another good architectural decision - they had the sense to decide that simple RF code-sending to the base station was good enough for the switch, rather than trying to make the switch into some kind of Wi-Fi connected thing running a TCP/IP and web stack (did I mention the switch needs no battery or external power of any sort?). The system stays out of my way and just works when I want it to, while still allowing me to dig in and add-on cool automation where it's appropriate.

The thing I don't get with 'control everything with your smartphone!' is that people don't think about everyday use. It's like the people that design these products don't look at the actual, repeated use cases. Why would I want to pull my phone out of my pocket, unlock it, find the app I need, launch the app, wait for it to connect, hit the buttons I want....

(Even when I'm on Android and I can have an IoT control widget on my homescreen, that's still pulling the phone out, switching it on, unlocking it with my fingerprint, finding the page, hitting the button.... oops I forgot to turn Wi-Fi back on, better do that....)

I think IoT is great, but to do a great job at it you need to design the product with that in mind to begin with. The whole architecture of the product has to fit (see again, Hue). Sure, picking an Android tablet is easy, but why would you architect all that complexity? Why not a touchscreen device with a really simple real-time OS that does only what it needs to do?

I'm confident that this will all be self-correcting in the end. Consumers and 'the market' are smarter than we give them credit for. Certainly it takes a long time for them to react, but I think that when enough of the public is jaded by 'bad IoT' and the fad phase has passed, the actually good IoT products will survive and those companies that really think about their designs as a whole will be rewarded.
