Holy shit, it's the Year of The Linux Desktop, for real this time. It's happening. It's actually happening.
A standard Arch Linux/KDE[0] PC for every home, in a polished, vendor-supported package. Like Apple, it's a single standard hardware/OS pair, so, FOSS' fatal hardware-support hell might well be made obsolete. The vendor is a household name corporation. There's an incredibly fortuitous (for Linux) market dynamic at this point in time, of "commoditize your complement"—the dynamic that Valve has incentives to invest massively in giving away a nice thing for free, because that does bad things to its competitors. And Steam is... the killer super-app to end all killer apps.
