In the next revision of MorphOS (probably 2.
we should see support for Powerbooks. 'Amiga' laptops anyone? Tablets? That can't be too far off either.
For a 'dead' computer, the market seems pretty lively.
The "Wolf"man will probably be along to point out to you that he does not think that PowerBook support will be included in MorphOS until a version "After" v2.8, due to some comments by some of the MorphOS Dev. Team members.
What ever version PowerBook support does come to MorphOS, be it 2.8, 2.9, or later, it will be a great day for Amiga users that are still clinging to the PPC architecture (like me, sort of, I have had AmigaOS3.x running on a laptop since around AmigaForever v2, on my very first x86 computer at home, an off-brand 400MHz Celeron laptop which I later upgraded to a 533MHz Celeron (as far as it could go)).
I am very much looking forward to running MorphOS2.8, or 2.9, or a later version if it needs to wait longer to get it right, on my 1.67GHz G4 17-inch widescreen PowerBook that I bought on eBay a few months ago in MINT condition, with a 2 year warranty. Having MorphOS on a great laptop like the PowerBook, where at 1.67GHz it is really going to fly, is going to be a fantastic step forward, and will get me using MorphOS much more than I do now, since I am unable to sit at a desk in a chair for more than a few minutes at a time, due to my back condition.
As for your prediction of an Amiga tablet being possible not too far off, unless it is an x86 table running UAE, I am not aware of any PPC tablets that would be candidates for AmigaOS4.x, or MorphOS2.x.
