The Vampire 500 V2 really isn't very far away from this idea already.
Simply add a LVDS for direct LCD display output, a USB hub, and some power management chips, then engineer it into a laptop chassis compatible form factor.
A cheaper and more interesting project, by a long way.
-Edit- I'm not trying to be negative, I just can't see any positives with respect to a PPC Linux laptop.
Yes, well I was being a bit of an ass, especially considering my core beliefs.
Beyond that, I know further PPC projects are not that practical.
I explored the idea awhile ago, and even got as far as enlisting Bill Buck who approached Freescale about the idea.
I am reasonably sure the PPC laptop will gain some traction, as the first step is quite likely to be financed.
And I'm one of the people that would want one.
Then again, I'm also one of the people that sees the value of the X5000 over the A1222.
But you're right that an FPGA laptop might have broader appeal.
I could see that being used for multiple cores, not just Amiga based projects.
Spreading out that way would offer an opportunity to enlist people from outside the Amiga community as well as having appeal to our core constituency.
The saving grace with the PPC project is the interest outside of the Amiga community, primarily from the Linux community.
But an FPGA laptop would have even broader appeal in multiple segments of the retro market.
Portable Amigas, Apples, Amstrads , heck I'm still in the 'A's'...the potential for your idea is massive.
Again, really sharp.
