I am thinking of the Amiga CD 32 here. It would have ended in rampant piracy, once CD-R got available and affordable.. or even much earlier, if adding a floppy drive.
You can even burn a CD with one hundred Amiga 500 games if you like.
So, there was a computer-as-a-console which wasn't quite locked down. It also seemed to come with previous-gen games!, even though there's no console version of the previous gen : repackaged Amiga 500 games with a CD Audio soundtrack were a cheap and easy way to release something, although the console has Amiga 1200 hardware which is more advanced (games for the A1200 aren't well-known anyway)
But had it been not bogged down in a patent lawsuit which also bankrupted and killed off Commodore for good, I am sure it would have been a popular and classic console, with a good few years where CD piracy wasn't too big a concern. Perhaps a couple millions to fight off the bogus lawsuit would have been enough, esp. if the lawyering had managed for the console not suffering a quite literal naval blockade. Of course by then Commodore had wasted way too much money and engineering on useless computers like the Commodore 16 and Plus 4 in the 80s and the CDTV in early 90s. If you wonder the latter is a "multimedia CD-ROM appliance" thing i.e. overpriced garbage that no one wanted, to read multimedia encyclopedias on the living room's TV and the like. (but add the missing keyb, mouse and floppy and it's a full advanced 80s computer)
I wonder if Commodore collected royalties for CD 32 games. I guess they did, for the logo on the CD case. But my guess is there would have been rogue and self-published games, that also happen to work in 32bit Amiga computers with CD-ROM drive attached. So, is that a computer game or a console game? Just say it's a computer game and you won't have to pay royalties (perhaps that's one reason banks/investors didn't chip in)
Dishonorable mentions : the Atari XE game system (outdated, can use a keyboard etc. to turn into a souped up 1979 computer), Commodore 64 GS (outdated computer with no keyboard. you can use old cartridge games and be stuck because you miss the keyboard to navigate the game menu), Amstrad GX4000 (too bad, it was cute and had a good color palette. But two buttons on the controller with no start/select in 1990?), Apple Bandai Pippin : multimedia CD-ROM with slow ass Internet!
Turn a console into a computer : this existed although usually disastrous. That was the Coleco Adam in 1983, and perhaps rarely the Amiga CD 32 (with third party expansions). The PS2 linux kit later ; Dreamcast was maybe almost there (keyb, mouse and the built-in modem), it sure did accidentally support execution of arbitrary code because they built some support for.. multimedia CD-ROM! Then PS3 had computer mode out of the box : effectively linux on a slow single core hyperthreaded CPU, 256MB RAM and raw 2D graphics. But that was good enough for people to like it, until that ended in removal and law suit.
It's possible to sell the upgrade from console to computer. MS has just announced something very similar, Windows 10 S is half way between a console and a computer like an iPhone/iPad iOS thing is. They sell a $49 "upgrade" (that is likely a glorified registry setting). I can certainly imagine MS selling a Windows 10 version for say $99 to run on the Scorpio. MS is also a good keyboard and mouse vendor (this is what I give them credit for
). I guess the piracy or unlicensed (to them) games, stores, applications wouldn't be a big deal then. The desktop and laptop OEMs would not appreciate the competition. MS would endanger its position by pissing off the Dells, Acers and Lenovos (/edit : as you said Jay on the first page). But as it was already said, the slow CPU is impractical. You'd get high end PC games running at a smooth 20 fps no matter the resolution.
