Yeah, let's calculate again: a $100.000 computer can serve about 10 people
running a curses (or similar) based application. For 50 people you need
5 times $100.000 of computer and 50 times $300 of terminals, or about
$515.000.
Now, with the application running locally in the terminal (and only talking
to the host in small blocks) you can easily run the 50 users on just the
one $100.000 computer. So all you need is 50 times the $2000 terminal,
or total of $200.000.
So especially for data entry, where the processing of the data is minimal
and presenting the forms and parsing the user-input is the hard part
the 630 (or old 5620 for that matter) is a real win.

Paul.
