The Q&A for FLL coaches says it comes with a rechargeable battery
system. I think I heard that it was Lithium-Ion in the shape of 6 AAs,
but you can use regular AAs. Whether it comes with a rechargeable
battery system might depend on which system you buy. There is to be a
retail version and an educational version.

Oddly enough, have you seen this:


http://www.firstlegoleague.org/default.aspx?pid=21400


Half way down it says that the NXT will have a:

          Rechargeable battery system

Will the "battery system" be a preshrunk battery pack with some
connector on it to plug into the NXT?  Could a hacker then find that
plug and plug a wal wart INTO the nxt?

Chris

YA, and while I'm wishing, maybe I can get  the NXT to generate next
weeks lotto numbers.
