Seconded! I started off on piano, after 7 years of lessons I decided rock was cooler so I switched to guitar at the ripe old age of 14. Then when I was 18 I borrowed my first drum kit and the rest is history... I have been in bands as a drummer, as a guitarist, and in fact just as a stand-up singer, and they're all definitely good experiences to have. Currently I share frontman details as guitarist and singer in my main band, but I also fill in for another band as a drummer from time to time.
Electronic kits are cool in theory but kinda "meh" in practice. Although, if you are trying to start out and you don't have any place you can be loud for a little while, they might be cool to look into.
Go for it.
