Oh, cool! I've always wanted a full-size keyboard to learn piano (then I could play with headphones in and not annoy my neighbors for hours, lol). I understand it, whereas guitar confuses my brain. XD
When I was a teenager I was over at my friends house for the weekend, and I camped out at their piano with their beginner learning book and worked through the entire book in an hour or two, however long it was, I'm not sure. I only stopped because my friend came out and was like ENOUGH COME AND KEEP ME COMPANY WHILE I CLEAN, but that's my one experience where it was "AHA!!!" instead of taking an actual guitar class and still being mightily confused.
