I received the keyboard yesterday.
It has all the notes written on it which I find quite handy. Was a bit difficult to get working at first, till I realised you have to select the keyboard in the options of whatever software you use.
Keyboard seems a lot quicker to learn than guitar. I'm not saying its easy, but so far I have learnt a few chords, the 12 bar blues and the first 25 seconds of moonlight sonata. In the same amount of time learning the guitar I could play the smoke on the water riff on one string.
I have been using Synthesia. It's just like guitar hero for the piano. Though I will be making a concerted effort to learn to read music next week.
Playing keyboard is really addictive!
