I would LOVE LOVE LOVE LOVE to open a box with a brand spanking new Amiga A600, with all that fresh new plastic smell, embozzed Amiga logo on the case, crispy new mouse, plug it in and it boots up to Icaros on X86. m68K is just dumb to try to build a new machine around, PPC is too damn expensive for the only benefit of running AmigaOS 4.1. PPC is just an ugly dead-end. x86 is the only affordable option forward, has the most flexibility for reusing the setup, and whatever… Just go x86 even if you have to use uae for backwards stuff.
I would pre-buy that this very moment without a single hesitation if they could get that price under $700, had a cool app store-like deal where I can go software for free or purchase. Make the ecosystem. One website to buy my thing, buy some add-ons, and get my software in electronic download form. Don't make me have to order a cardboard box to come in my mailbox with a shiney disk that I'm then forced to load via a stupid CD-rom drive that I ALSO have to buy and setup. That's hyper stupid in 2012. This also makes it super easy for hobby developers to make cool apps for sale without having to worry about HOW to market, press, and distribute it. Like Aminet, but people can get paid.
I would like a HD option, but the base could easily be Compact Flash-based with two slots on the back. I would want to be able to simply plug in a CF card with any OS I wanted for the moment and rock out. Add USB ports in the back, stereo sound, and DVI or VGA out. Sell optional external floppy drives, CD-ROMs, etc, just keep that heavy and power-loving crap out of the case itself. Then if possible integrate the power in the case and I'm happy as a pig in poop.
I would buy this now!
