Oooh troll thread ahead! 
But well, to be seriously, not really.
Though, custom chipsets, and an OS which takes full advantage of the hardware, and both being designed for nowadays purposes, is something desireable IMHO.
you mean.. like the Xbox , the Weee, the playstation... etc etc
so on the one hand I do agree, on the other hand.... I'm pretty happy with my macbook pro and my core2duo general purpose box and don't see the point of any new amiga-like architecture
