Tension,
While you don't get "rid" of Windows, I've been extremely happy with the slipstream XP method. Boots right into WB, no muss no fuss. After configuration as per the guide you can opt to never see Windows again.

But it still suffers from all the problems of Windows. Just because you are running WinUAE does not mean you are not getting hacked over the network cable or get a corrupt 2 byte file in the registry that stops it booting

As far as MOS or OS4 goes....I'll wait until someone writes a PPC G4/G5 emulator core and then lets me run either of those systems via some sort of OS4 emulator

I have no interest in running OS4/MOS on hardware that is worthless to 99% of the world of computer users in reality.
The price of the x1000 is not the only problem, none of these Next Gen 'Amiga' solutions will actually replace a REAL Amiga than a PC running WinUAE at all, and what am I supposed to do with my 300+ original Amiga games.....exchange them for cracktros from Planetemu.net? No thanks

As long as you are not retarded enough to buy Amiga Forever (you are entitled legally to use downloaded roms if you own that version of Kickstart in an A500/A1200/CD32 FACT) then WinUAE OR a REAL Amiga is the only options AFAIC
