Well, I played an acoustic for lessons at school, then I got an electric and started taking private lessons. I have a hard time strumming on an acoustic, I need to work a lot more on my picking technique, the thinner strings on the electric got me lazy, I only remember to hold my pick right when I have to play triplets. I would say, though, that if you have songs you want to learn that are pretty much only electric songs, get an electric, playing songs you like is the most important thing to keep you going.
