Day one update:
I love the hardware. It is small, quiet, and easy to use. I turned the alien led off so it looks a little less tacky. The custom UI is nice and simple to use as well.
That said, Steam Big Picture mode is a pile of hot garbage. It makes it simply impossible to use the Alpha without having a mouse and keyboard handy at almost all times.
I'm still really liking the hardware, but definitely can't see this micro pc/console being someone's only gaming system. It is just a bit too clunky as many games listed as being controller supported still need mouse/keyboard and Big Picture Mode being garbage.
I'm going to experiment with New Vegas mods tonight. First I have to figure out how to find and install mods.
