Been a long time since I've logged on here, but I'm pretty much with Plaz on this: give us something either 68k-based or PPC-based, capable of running real, actual AmigaOS, not some kind of AmigaOS-lookalike running on top of Linux on an x86 like your PC64 is to the old C64. Maybe hook up with the makers of the NatAmi and make an A1000 and/or A1200 replica with that in it, or get with Hyperion and work on getting a variation of what will be going into their upcoming Amiga netbook, but with an A1000 or A1200 replica wrapped around it, or some other kind of desktop machine with one or the other of those in it. Heck, do both a NatAmi version AND a version with the Amiga Netbook mobo in it.
