I can't buy an AmigaONE any more, the SharkPPC may not come out (and my a1200 is quite overburdened as it is and what if rare parts of the steup go pop), i have several PPC macs, and loads of people out there loved amiga mes, SO:
0. Get something like UAE / WHDLoad that is under the LGPL and integrate it into the OS to allow running of metal banging games (from images) and apps (from executables). Petunia as i understand would not work with metal banging apps, but could easily provide the CPU emulation. Make sure it allows multitasking.
1. Release an "Amiga Classics" title for the Wii, Playstation, and XBox 360 (all ppc i think) to milk funds from those who loved the Amiga in their youth, but treated it as a console. Such compilations (e.g. Atari, Midway) have done well before, as Retro-Gaming is quite chic. Give a percentage of the royalties to Team 17, Bitmap Brothers et al.
Provide the user with an OS4 desktop and hard drive / flash persistance if a USB keyboard and Mouse is attached, else display a nice menu. All these systems have copy lockouts of some sort, so piracy probably isn't a concern. If it is, only allow use of the desktop with a USB dongle attached.
If needs be, don't bother with this step until later to get some cash roll in (just make sure to identify the desktop enabled version clearly on the packaging, and maybe jack the price accordingly).
2. Release OS 4 for the "new-world" G3/G4 Macs (especially for laptops!). Provide a (small!) USB encryption lockout dongle (which could be sent back when the user wants to upgrade to future major releases), a protected OS CD-R (tied into the specific dongle in the package). Do similar for Pegasos, Efika etc.
Provide well printed packaging, install notes, and some stickers in the package. Sell it for 150 GBP (i'd DEFINITELY buy it!)
Sell image conscious geeks custom lids with a (glowing) Boing logo for their iBooks / Powerbooks (free advertising for them for people like me on trains etc)
3. Do a deal with Opera to supply the browser (to keep Nintendo happy if this is a concern). Also do a deal with nintendo to allow sale of Amiga Games for the virtual console.
4. Make sure the geeks get their X11 server, VNC client and server, SSH client and VPN client to keep them happy.
Don't bother with multi-user extensions to be more UNIXy; pretty sure most people would be happy with the idea of a Personal OS. Add a JVM with native GUI hooks (like in OSX) if possible. Other software such as a widely compatible media file player (sell it as a PVR?) would be highly desirable.
5. Continue to supply support to the "faithful" users of Blizzards, AmigaONE and Shark PPC's (give them a Cheaper OS, especially for AmigaONE owners who have the encryption hardware built in i think).
6. Don't bother with X86, too much work has been done on PPC, and most of the target market would have the hardware (be it a console, a possibly-now-spare-PPC-Mac as they've gone intel, or a specialized amiga system).
7. Once your "brand" is back to where it should be and you have loads of $$$, quit messing around with those lame phone and wince games!!
Anyone else have anything to add / pooh-pooh / flame about?
