It seems like a gimmick because the aesthetic quality of turntables is part of their appeal. It's just more interesting to see a DJ flip through vinyl than to scroll through a list on a laptop. But with djay 2.1, only the person working with the software can see it. However, it is that aesthetic simplicity that makes the program easy to use.
Unlike a program such as Traktor, which has far more versatility, djay 2.1 isn't intimidating to beginners. Within a few minutes bedroom DJs can begin mixing tracks together and creating simple effects, such as scratches, loops and reverse. It's not the program for a full set out at a bar or dance club, but as an addition to a variety of instruments or as an easy way to practice at home without pulling out heavy and expensive gear, it's worth the small download price.
