I'm trying to understand what makes this *Point-of-Sale* (POS) screen design look dated.

Is it the 3D buttons, the colours, the layout, the font? And what would you do to make it look current?

Not being a design professional, I can see that it is dated. But I'm not sure why and how to change that.
