+Q12: I often need to stop my player for about 15 minutes or so, and when I do
+     it runs off it's batteries.  I was wondering, which is best: shutting the
+     player down completely and rebooting it when I want to listen again, or 
+     leaving the unit on?  Which way does it draw more power?
+A12: In our testing we found the following results:
+         HDD off, LED off, idle 94 mA
+         HDD off, LED off, play 97 mA
+         HDD off, LED on, idle 129 mA
+         HDD off, LED on, play 131 mA
+         HDD on, LED on, play 230 mA
+         HD on, reading, LED off ~ 600 mA
+         HD spin up before read max 800 mA
+    
+     So leaving the unit on and paused consumes ~100mA, and thus much less then
+     needing to reboot the unit.  Your mileage may vary.
