These things are still being developed! It looks like the latest one was the A1222+ which also came out last year and costs somewhere north of a grand but it is An Amiga with a 1.2GHz dual core CPU and 4GB of RAM

The emu box I mentioned is the A600GS which is ARM based & it seems to use their own frontend on top of AROS which is an open source reimplementation of the AmigaOS API and not connected to OS 4 which is closed source & based on the original Commodore code. AROS also has an Eric Schwartz mascot
