[AFMUG] AF5 vs AF5X

[Ken Hohhof]

Can someone point me to a concise explanation somewhere of the difference 
between AF5 and AF5X?  Where you would use each, and what you give up with 
the X in return for smaller, cheaper, lower power, and drop-in replacement 
for a Rocket?

I know it doesn't have the built-in high isolation TX and RX antennas, and 
doesn't do a gig of throughput.  But I'm sure there's more to it.  It's not 
jumping out at me on the UBNT website.
