With battery technology getting better and better, and with the laptop market already doing this, why aren't PSU manufacturers building in some kind of battery backup for desktop PCs?
I'm not talking some multi-hour deal, but something with just enough grunt to give your PC 5 minutes to shut down should be enough, right? It wouldn't even need to power the peripherals or the monitor as you could bake in a shutdown sequence, like with UPSs, to put the PC in a hibernation state.
I dunno, just an idea that's been bouncing around my head (might be a good topic for an ltt or techquickie video)
