I still use a 14" iBook, so I can't personally see any interest in anything bigger than 17", but I guess if you need a desktop replacement (and you don't wantto carry a second screen around with you), 17" can seem small...
I'm with nxnw on this one, when I picked up my 15" PB I looked at the 17" and thought it was too big to be hauling around. Making them even bigger? I knew it would happen, I just don't see it being a big seller, it would just be too inconvenient.
Who here would actually be interested in a 19" or 20" Powerbook from Apple?
Maybe if you could fold it in four
(Somewhat) seriously though, think of the possibilities... Two 10" spannable screens, a split keyboard (bye bye tendonitis). Of course you still have the problem of fitting it on your lap. Then again, aren't airlines thinking of widening seats to accomodate the new "supersize" of the average passenger? Never say never.

17" borders on functionality, A 19" or 20" laptop would likely be too large to carry "may exceed cary-on size for airplanes". I would also hate to see what that size of display would weigh. Lets not forget the battery power that would be required to power such a beast. I have a friend with a 17" toshiba that with all accessories likely weighs in at about 10 lbs. Have fun lugging that through an airport.
Whats wrong with using the laptop in closed-top mode. Why not buy two 20" monitors in the two places [work/home] where you need a large dispaly.
