There's so much hardware out there... you got Arduino's, lots of clones, Raspberry Pi's, C.H.I.P, etc.
What they don't tell you is how the software is. Is it up to date, or does it still run Linux 3.x? What Linux distros does it run? Can you run stock Ubuntu, or do you need some guy's custom build that's two years old and you can't apt-get upgrade?
My specific beef: It looks like the VoCore2 rans OpenWrt. Which version? Custom build that's updated every six months?
And, thanks to Indiegogo, you can't post a comment (to ask a question) without contributing. What a bunch of bull.
