A couple of more newbie questions
1) is the iliad stylus also powered by a battery inside of the stylus that's
charged at the same time the reader is charged ? If so, is there a battery
indicator for the battery inside of the stylus ?
2) how many hours of battery life should one expect out of a iliad 2nd
edition with firmware 2.12, under extremely heavy usage, i.e., playing
GNU Chess (I think I lost 20% of battery just playing GNUchess alone for
about 5 min) while listening to MP3 played by Jukebox 3.1 and fed to an
earphone, or web browsing while listening to MP3 the same way ?

1) no, there is no battery in the stylus. As I understand, it's like thoose tags the shop places on it's items to prevent them from getting stolen

Well in this scenario you use three things which decrease battery time and are not considered in iRex's average battery time.
# sound card is enabled
# digitizer is enabled [because you use the stylus]
# chess engines produces high usage of arm processor

1) The active component of the digitiser is in the screen itself. The stylus is totally passive. I think it may have a magnet or something similar in it ...

Roughly speaking the stylus is an oscillating circuit, the iLiad send out an electromagnetic impulse, this induces the circuit, the circuit sends back an altered electromagnetic impulse with information coded in like pressure.
Yes this is roughly speaking the same tech as what shops use to protect their stuff from getting stolen.
