One of the great advantages of the Arduino UNO, IMO, is its simplicity.
Simple to buy (Micro-Center, and by mail order), simple to power up
(USB), and simple to program (a pared-down version of C).
Also lots of books and articles available.
Once we go for higher-power processors, etc, then we may as well forget
about simplicity and attractiveness to your average Ham operator.
(That's is what I am trying to encourage: your regular ham deciding to
buy an Arduino UNO and connecting it to his/her USB port).
