Two-dimensional keyboard layouts mostly use regular chord shapes. It makes both theory and playability come a lot more easily - two fingerings per scale and chord, no adjustments for different keys. I own an Axis 49 and while I'll admit it isn't perfect for existing repertoire, it excels in every other respect. If you want to "learn music" this is the fastest way to do it.
