I'm not the least bit interested in this system, but equally I don't hate it or anything.
The only reason I'd be interested in a C64 for is the SID chip as an interesting noise making device.
The Commodore and Amiga we know and love are long dead. OS4 / MorphOS / Aros will at best give you a similar desktop experience. UAE will give you the retro experience or if you're really fussy you'll need an FPGA based system (Minimig / FPGA Arcade / Natami). If you're really really fussy just buy a classic machine off ebay.
Note that none of those in production today are called "Commodore" or "Amiga". They are just names now and if someone wants to make money off them good luck to them.
