I am sure that would work great. When I walk into a lecture hall, I just need to tell everyone to move over so I can plug in my external display.
Is 17" laptop really required for lecture halls? Most people find even 15" too large for these situations. But I digress, I'm not saying Apple is right - or wrong - I'm just trying to analyze the situation.
I believe this is Apple's reasonong (again - don't convince me it's wrong, I have no personal opinion on this, I'm just "guessing" what Apple's views are): if you need more than 15", you should be at your desk. For everything lese, 15", 13" and 12" are good sizes for 99% of people.
Personally, I wouldn't mind a brand new 17" MBP. But I highly doubt Apple will make one.
