For me the Amiga as we know it is still alive but only as long as users like us keep it alive. Emulation has come a long way but still will not run the amiga hardware. The Amiga One was a nice try but again is not compatable with alot of the old software or hardware and apears to be a short lived creation as there are no plans to continue making them.
Thanks to people like Amigakit we still have support for Amiga and parts are still available. As long as users try to keep there Amiga alive it will continue.
