The main reason I didn't bother getting a VL-1 was the button type keyboard...of course, the sounds were rather cheesy, but, sometimes that's just what a song needs, as illustrated in the video clip.
Today's arrangers are phenomenal, with all their incredibly realistic sounding (and very expressive) SA/SA2, DNC, and SuperNatural sounds.
I bet a lot of VL-1's ended up in Xmas stockings, and no doubt, the first tune played was "Joy To The World".
