It's a fair point but I guess I can't wrap my head around it. Within a square foot you get at least 10x the capability and expansion of a Pi.I'm probably limited by my own perspective and bias but I can't understand someone not being able to find a square foot for a device that can replace any number of things, in my case even my router. Inch for inch they can't be matched but I suppose if you really only have a few inches a Pi is your best bet. I'm just glad I'm not in that situation.
I did reference the "mini/micro" variants which are significantly smaller - with the sacrifice being loss of PCIe which when it comes to x16 + x4 slots there really isn't any way to get around. Mine can also take two 2.5" SATA drives depending on how you feel about that.
