It also failed because they had to stop producing it due to some patent troll.

I still have mine and I agree. Though I do like the changes on this new one to more mirror the steamdeck.

Mostly yes, but it wasn't flawless. Those trackpads are quite loud (compared to the Deck), the ABXY buttons are a bit too small and awkwardly placed, and there are just many times that I want a second thumbstick. Also it lacks touch-to-engage for the gyro but that's a newer invention.

I think the most impressive innovation came from pairing it with Steam Input. That system is still wildly underappreciated; it's what lets you turn the trackpads into things like custom radial menus.

I felt like replacing one of the two sticks with a trackpad just ended up being the worst of both worlds. You don't get the accuracy of using a mouse and you don't get any of the design benefits of having twin sticks. The vast majority of controller supported games are designed with twin sticks in mind. Crimson Desert is a great example from recent memory because I can't imagine doing circular motions on the right trackpad, which is what you need to do for one skill and the fishing minigame. My thumbs are too lazy for that. But with a stick that's easy enough to do. Overall fighting games are harder, flying games are harder, twin-stick shooters are almost impossible. Any game that requires some stick-like movements from the right stick instantly get harder to play.

I'm not hating on the Steam Controller, there were quite a lot of innovations I would've loved with twin stick controller. The return of the twin sticks is the main reason I'm excited for the controller. I'm also happy with the Dpad coming back because I always felt that was also somewhat clunky on the first controller. Overall I think this one might end up being GOATed.

I use mine every day. Also, it never failed.

I have it. The original Steam Controller is not really a good controller in my opinion. It has huge flaws, such as holding it for longer period of time starts hurting my hands, the missing dpad and missing second stick, and the weird sound it makes when using the touchpads.

The thing that killed it for me is that the touch pads were just terrible as replacements for the dpad and right analog stick

I agree, although I believe it was:

60% society not ready for the awesome

40% people with small hands

I love my steam controller, but to me it wasn't a good replacement for controller games. Don't get me wrong, it's great and the ONLY alternative to play non-controller games (and I put FPS games in this category), but trying to play most games that waere actually designed for a controller always felt off. The lack of a proper d-pad made it worse for pixel perfect games like Dead Cells, and while the track pad is great for aiming by emulating a mouse and adding gyro, most games also use the thumb stick for mini-games or something that feels weird with the track pad. And yes, I know I could setup layers to solve that, but it's just easier to grab another controller.

On the other hand, since I held my Steam Deck I've been wanting a controller that was the exact same thing. It works 100% like a normal controller, plus has 2 trackpads and 4 back buttons. They fixed every single issue I had with the OG controller, kept everything I loved about it, and even added some things I didn't knew I needed (extra back buttons, capacitive gyro, etc).

Fully and entirely correct.
