I'd rather have a NatAmi than an X1000. The NatAmi will run more Amiga software than the X1000 ever will unless things have changed dramatically with the design of the X1000. EUAE stinks on OS4 due to lack of a JIT.
If raw brute force is needed, I'll just write an Erlang to VHDL converter and bang the bare FPGA on the NatAmi. I think that's not even an option on the X1000.
Popcorn anyone?
