    Frank you have forgotten one thing about the smartphone
    and the battery is dead after one day.


    My TI-89 calculator works a year on a set off battery's (4pc AAA standard batterys).
    My son uses a TI-84 on the high school every day. He had to change the batterys after 1½ year.
    Thats the greatest pro between calculator ans smartphone.

    Bur everybody can use what he likes.

    regards. HermanD
