I tried kite a few years back in a attempt to replace wakeboarding because I didn't have a boat. It was fun, but it didn't do it for me.
Equipment is expensive and you are a slave to the wind that can be somewhat unpredictable. Going up wind can be a pain in the a$$. I like the fact that I can take my boat and ride any place at any time.
The board skills will come natural, but it will take time to understand the kite aspect unless you have windsurf or sailing experience. +1 on taking a lesson.
