Like everyone else, I mostly remember being amazed by both the graphics and the price. Nobody I knew had one, except one guy who acquired it using money he'd raised through, shall we say, illicit means. As such, he kept it under his bed all the time in case his parents ever found out and nobody saw it. Come to think of it, he may have been making the whole thing up...

As mentioned elsewhere, this was the first system I was enthusiastic about emulating.
