Hi For a lot of what we do, having a board with 16 GPIO's and a couple of UART's pinned out is probably more important than 1.2 vs 1.7 GHz on the CPU(s). A lot of the Korean and Chinese boards seem to be aimed at driving a TV for streaming video. All the other stuff is probably still there. Getting at it on the bottom of a BGA - not so easy. The i/o connector on the Pi has it's issues, but at least it's there.
Of course for timing applications, having a couple of timers and some high speed capture pins is the ultimate goal. Externally accessible >=32 bit timers driven off a > 1 GHz clock would also be nice. I suspect all that's going to be a bit hard to find in a cheap generic board. Since all of these boards run a fairly complex OS, we'd also need kernel code to support them ...
