Incidentally, don't confuse Amiga Inc. with Amiga OS. Hyperion update AmigaOS 3.1 up to AmigaOS 4.0 and it's an amazing OS now. If you want to use an Amiga then OS 4 is the way to go, the only problem is:
a) Finding an AmigaOne to run it
b) Getting a second mortgage to pay for said AmigaOne.
So don't give up all hope on using a new Amiga, it's very likely a new AOS 4.0 compatible will be out at some point in the nearish future, just no-one knows when!
