We've got an ODroid. The impression I got was that the hardware was 
fairly well done, but that the distro that came with it (some variant of 
Ubuntu) rather less so... the usual things about missing dependencies 
which can make things very flaky (e.g. autoremove broke X11 beyond repair).

My recollection of the UEFI situation is that Intel et al. made "Secure 
Boot" optional on PCs but mandatory on ARM systems that had UEFI.
