No, sorry it isn't anything like it. I've used AROS and since my first try i have stayed FAR away, its so unpolished. Also, any X86 HW available is nothing close to an Amiga, nowadays, taht belongs to the SAM and G4 macs, since MOS has better compatibility than OS4 or AROS.
Sorry, but I can't agree on this. There's nothing but the processor to distinguish a SAM or a Mac motherboard from a plain PC one, and from the hardware point of view you will find the same BUS, ports and connectors on any modern machine, being it x86 or PPC based.
We can argue the X1000 will have a programmable logic on board. A-Eon is struggling to convince us that this is a real heritage of the Amiga custom chips. You don't need a degree in Hardware Specialist to understand that's not the case.
Let's be more philosophic: Amiga was great thanks to its awesome multimedia performances opposed to a cheap price. There's absolutely nothing of this in SAM or X1000s. And any comparison between
used Macs and new hardware is quite unfair. A long ago, playing at the edge of bitmap graphics, color animation and sound were attractive keypoints, but today needs are changed. Now people needs communications, weareability, lightness and autonomy. Computers (and not smartphones, or MIDs) that satisfy those needs at cheap prices are netbooks, and that's why IMHO my Aspire One is the heir of my old Amiga 1200. It's cheap and fullfits my needs.
About AROS, in the end, I can only invite you to try the latest releases, since they are much more polished than, for instance, one or two years ago.
And, not for you but for the one immediately after: netbooks hardware may be crap, but they give you much more than you pay for. I don't know if you can tell the same thing about any AmigaOS-compatible PPC platform. And you should really give a try to AROS on singlecore Atoms to believe how good they can be with a light operating system.
