Except for the flakey MMC path... The dock SD card reader is an USB one,
which uses a totally different path in the kernel.
eMMC seems to be good. MMCIO (internal Wifi) is flakey. MMC may be as
flakey as MMCIO (they're closely related).

I didn't use Windows too much. I vaguely remember noticing strange
behaviour with the USB ethernet dongle, like random USB disconnects.
That's not too problematic, since the network gets back up cleanly and
quickly. It may be related to the same problem though : random
disconnects of the whole dock, maybe because of the connector, maybe
because of the embedded controller.
I wouldn't (and didn't even try to) put a root filesystem on a doubly
removable media though ;-)
