Ok, well that's interesting - would anyone else like to comment? Speak now or forever hold your peace :)
The through-hole JST connector I've seen (the one in Seeed's OPL and the one that Olimex use) is rubbish (there's no support at the front at all). I think this one's actually pretty sturdy - the thing that killed the USB was that there's twisting force because the tabs aren't right at the front of the connector - the JST doesn't seem to have that issue. The pads are much bigger and the connector that plugs in is much smaller.
On the new board:
4 pin through-hole USB
32kHz crystal pre-installed (hopefully)
New voltage regulator, which should at least halve the power consumption in deep sleep mode. It also raises the max input voltage to 20v.
Otherwise I'm trying to keep it mostly the same...
