From my personal experience watching my own children use gDocs, they're
extremely comfortable working with computers in general and the operation of the tool itself is nearly transparent.
They open a document and start typing. They open a slide presentation and start moving pictures and words around. Collaborative work is automatic and they kids don't even think about it. I can remember a time when simultaneous editing of a document was something only CS PhD students dreamed about in their theses. Now my 7 year-old is doing it. And she finds it kind of fun, actually.
It doesn't need to be an indoctrination into corporate life and I haven't seen one iota of that in the classroom. They're just tools like everything else in their school.
Is writing on a whiteboard training for the business world, or just an easier/cleaner way to write so the whole room can see it? How about using a video projector overlaid on the whiteboard? Sitting on an exercise ball to minimize fidgeting? Standing desks? RFID cards in the lunchroom? Maybe they're all just applications of technology that have positive uses with the kids.
