[SATLUG] Alternatives to Raspberry Pi

Joe pretty much nailed it. The RPi can be interesting if you go in with
REALISTIC expectations. But a lot of people see it as a 35 dollar full
fledged computer that they can do everything with, and that just isn't the
case. My biggest beef with it is the USB issues (lack of power) - and
while the B+ fixes *some* of those issues, I still have problems plugging
in 4 USB devices. Not to mention that the storage is sdcard (or (on b+)
microsd) which is slow. The bbb, for example, has eMMC, which can be much
faster, although on the bbb, you have only 1 USB port.
