I am a guitar player currently teaching myself some scales on the keyboard I just bought. I eventually want to get lessons. I am 20, a college student without a lot of space. Obviously, I would prefer a real piano, but can neither afford one nor have a lot of space. How much am I missing not learning on a real piano? Jazz is my favorite genre for piano, but I also like contemporary music and classical.
This is the one I have:

The digital piano you have should be just fine for learning the basics. Take advantage of the built-in learning features it offers.
From what I could tell by the description the keys of this instrument are not fully weighted. This means that they will not feel like a real piano.
What you can learn on your keyboard is basic fingering, chord patterns and limited expession.
What you are missing is the full, rich expressive sound of a real piano and foot pedals such as sostenuto and incremental damper control. Your sustain is on or off but on an acoustic piano you can get some in-between effects. The other thing you do not have is a full 88 key range. This will probably not be an issue unless you are playing certain classical pieces written for the piano.
