I have one and I would NEVER go back to cable steer. There are so many awesome features that I use every time out. Basically you have a remote control boat. Think of all the things you can do...
Spotlock... wind, current, it doesn't matter, you're staying put.
Autopilot... Set the course and speed and it will keep that heading no matter the wind or current.
Find a spot in the middle of the lake you want to fish? Hit the Spotlock upwind of the spot, wait for the wind to turn the boat and go to the back of the boat and fish.
Need to go back to the truck for something on a windy day? Drop yourself off at the dock, use the remote to drive the boat out a hundred feet or so, hit Spotlock, and go to the truck. When you return, drive your boat to the dock and pick yourself up.
Buy one with ipilot. You won't be sorry.
