Will new mac laptops still boot in os9?

Well, it is not Jan 2003 yet so the answer is "Yes, provided you own a copy of OS 9"

 

As I've said before, when you buy a laptop now, you will get both OS 9 and OS X...so the answer is yes.

And yeah, its not 2003.

 

Probably, but the energy saving and system cooling features are deviating more and more from the final installment of OS 9 - since the OS ROM file isn't being updated, you can't take advantage of these features.

Expect the next major motherboard revisions of computers to completely break the systems bootablity - not talking speed bumps here.

 

Just watch how you word that... the PowerMacs and iMacs do NOT have OS9 standalone, only classic and I would say the new machines would be exactly the same... you have to buy or install a full blown version of 9
