If you need an Amiga laptop surely it would be useless for work?
If someone can persaude IBM to ressurect their PPC based Thinkpads ( last seen 1997 IIRC ) and someone steps up as reseller to license them for AmigaOS then it would cost the same as a normal laptop.
Alternatively the same for PowerBooks, no reason someone couldnt set up a license with Amiga to resell on Powerbooks in quantity with AmigaOS. If they have the capital and the business plan.
Possible, but not probable.
