sherringon456: Gabe newell is a hypocrite. I remember reading him saying something about windows 10 or windows 8 somewhere where he said he feared windows was becoming a closed platform and that steam OS would be 'open'. Now, an operating system, which as far as I know only lets you play steam games, now that is really open isn't it...
Fenixp: Source? I always thought Steam OS is just a Linux distro with Steam integrated, not that it can't run anything but Steam games. I'd like a source on this being planned, not on how it works right now - IIRC they're still in alpha.
It should be like that - Steam integrated, but with ability to run and install "other" sowtware too. Its debian based after all. though repositories for non game software said to be pretty poor.
Niggles: Will going AMD get around it?
Solei: I don't think so. New AMD based systems with win10 preloaded will show up too. Your best bet to avoid this is to buy motherboards where these new 'enhancements' can be disabled in BIOS. Check laptops before buying, and If you accidentally do end up with a laptop with a secure boot function that cannot be disabled, get a refund asap.
First they force strange functions like Secure Boot in Not-so-simple-but-still-good UEFI...then they gradually drop mandatory option to disable Secure Boot.
I guess NEXT step will be mandatory Secure Bot always on mode with NO way to turn off. Sooo, Win Only, Windows Store as only software provider, some other crap like TPM module and we all hail to Microsoft.
