Price would be a huge determining factor.
While you can indeed buy a powerful commodity hardware laptop for a few hundred bucks, that's not the machine a NG Amiga running would be competing against.
We are, after all - in a market where one can buy a top end PPC Mac laptop off eBay or local classified ad for a couple hundred bucks any day of the week. Add $100 for a registered version of MOS. I could find you 15 top end PPC Mac laptops for under $200 just in my locale alone on the various for sale websites like Bargain Finder, Kijiji, and eBay.
A $2000 OS4 based laptop would be a very hard sell in this market, even to the most ardent of OS4 fans - which I am one of.
