I am interested in buying 300D.
but i know from http://www.dcfever.com/reviews/Canon/eos300d/ that 300D does not have some of the above functions....

Is this a big problem?
are the functions so useful?

Please help me.
Really want to know.
Is there anyone here who is using 300D?
What do you think ar?
