Anybody messing with teh new Arduino Yun?

[Terry Fox]

While I was out of town, Arduino apparently released a new board, the "Yun": 
http://arduino.cc/en/Main/ArduinoBoardYun

This board has a small AtMega chip, but also has an embedded Linus chip, 
along with wired ethernet and wifi.  For only $72.

Has anyone had any experience with this board yet?  It looks like an 
interesting proposition.  A Raspberry Pi without the hassles?
