Well, I have to agree with you there. I've been in this situation many times
- the situation where heads-down data entry is involved. And yes, a slick
GUI does not meet EVERY need in computing, much the same way green-screen
apps didn't either.

However, I can't say I'll ever go back to DOS. I'm finding that a lot of
data entry is being done in GUI (with simple entry fields) and the aid of
barcode scanners. Another big hit seems to be touch screen GUI apps (assuming
the system doesn't require major amounts of typing). Most restaraunts seem
to be using this format now.
