    Looks like my message got lost in the aether. Apologies if this resembles something you have already received:
    In a message dated 2/19/2005 10:37:38 P.M. Central Standard Time,
    Yes, this is one of those Celestaire things mentioned above.
    Weight 3 pounds.
    And I afraid that it consumes power like my stupid laptop,
    which converts all this power to heat so that it is painful
    to keep it on my laps:-) And accordingly, the super-powerful battery
    hardly lasts more than 1 hour.
    Alex - If Ken listed a weight of 3 pounds in the Celestaire catalog, it was shipping weight. My TI 89 with snap cover (all about 5 - 6 years old) weighs about 264 grams with batteries (batteries account for ~ 100 grams of the 264), and battery life (4 ea. AA batteries) by my poor memory is somewhere above one hundred hours - maybe several hundred. But the capability is an order-of-magnitudes leap from an fx-250 or 260. The text on my 89 was inconveniently small, and the StarPilot program increases the characters to a comfortably readable size.
    Regards, Marvin
