i have several fake books, old ones. I never bothered with the Real books, but I do have the iPro on my phone and think it is great. But my favorite is still the little blue 400 plus page Pocket Changes. I used to carry two during my casual gigging days. The piano players always loved having one. No melodys, but who needed them? It was a given that everyone knew the tunes and even the lyrics in many cases. Now I keep a copy near my lounge chair for quick reference, bridges and tags. There's there's something comforting in holding something in your hand that is clear, concise and doesn't blink.
