I'm also a THEC64 owner, and I call it "retrocomputing on easy mode". That's a good thing! It offers a good-enough simulacrum of what the C64 experience was like. The breadbin case with original-layout keyboard, which feels plausibly like one of the keyboards that shipped on actual C64s (there were a few different ones), really put THEC64 over for me. And it just works with modern equipment like HDMI displays and USB controllers. It's a great way to introduce kids to the way we computed back in the before times.
