He shipped enough clunkers (and terrible design decisions) that I never bought the mythification of Jobs.

In any case, the Deck is a different beast. For one, it's the second attempt. Remember Steam Machines? But also, it's very much an iteration on pre-existing products where its biggest asset is pushing having an endless budget and first party control of the platform to use scale for a pricing advantage.

It does prove that the system itself is not the problem, in case we hadn't picked up on that with Android and ChromeOS. The issue is having a do-everything free system where some of the do-everything requires you to intervene. That's not how most people use Windows (or Android, or ChromeOS), and it's definitely not how you use any part of SteamOS unless you want to tinker past the official support, either. That's the big lesson, I think. Valve isn't even trying to push Linux, beyond their Microsoft blood feud. As with Google, it's just a convenient stepping stone in their product design.

What the mainline Linux developer community can learn from it, IMO, is that for onboarding coupling the software and hardware very closely is important and Linux should find a way to do that on more product categories, even if it is by partnering with manufacturers that won't do it themselves.
