If you want an Amiga that can run a lot of software and is 'backwards compatible' then you should get an A4000 with a PPC accelerator. If you already have a PC then I can't see a reason for you to go looking for an AmigaOne.
Stick with the classic Amiga. There is much more software and hardware available for it, and it has the true spirit of Amiga to boot!
