That's the thing, I do care about all of that. But it's still a very expensive deal for what you get. That's why I was very interested in it, but the price/performance scared me off.

The only thing hard to match right now is the small form factor. But honestly, that's not the primary selling point of this thing that most gamers care about when they're happily purchasing consoles or pcs several times the size.

Everything else it offers is matchable or handily exceeded with a pc build you put together (or let someone put together for you). Just today LTT put out a budget build video that doesn't do anything complex to reach essentially double the Steam Machine's performance, for the same price. If you want to fix the minor things they compromised on you end up maybe paying 100/200 more. Sure it's a tiny bit more expensive, but when you get twice the performance out of it it's an easy deal to make. Especially given that it means you'll make the build last much longer, and it's more easily upgradable making it much cheaper in the long run. And you still get all the benefits that you mentioned that the Steam Machine offers (especially if you install SteamOS on it, which ended up running better than on the Gabecube as it showed an apparent bug with quick-resume).

The comparison to consoles makes the Steam Machine a bad deal for those who just want a console-like experience. For those who care more about PC gaming, it's a bad deal due to the bad spot it sits in in the price/performance curve. This narrows the target audience to a very small sliver of gamers, who then need to be willing to shell out that much money on an already dated system that will be harder to upgrade in the future.

You don't really get enough performance for the AAA games, and there's cheaper out there if you're just an indie enthusiast. Given the pretty overwhelmingly dismissive response from the community, I doubt this thing is going to sell very well.
