Yea you get what you pay for. Don't get me wrong, I still like my raspberry pi. I just don't use it as a workstation/media center. The only thing I've really done with it is setup a digital voice server using Asterisk and FreePBX. It was pretty cool because I could use my google voice account for incoming/outgoing calls(free).
It looks like there' a version of OpenWRT in development right now for the Cubox, but no official images in sight. OpenWRT is MIPS-centric, and the Cubox is an ARM platform so this doesn't surprise me.
