Guitarists who have actually played Ebow over the years is, for example, Eddie Van Halen and U2's The Edge.
I tested the thing. It wasn't really that easy to learn how to handle it though, but my friend spun off like a cat on his Gibson SG. Wonderfull melodies and amazing sound-effects just blew my mind. It's hard to actually explain how Ebow sounds, but you can check out the YouTube-clip below, it might help you to understand what you can do. The guy playing is Phil Keaggy a real super pro.
Phil Keaggy is otherwise best known as an awesome "finger-picking" guitar player, considered by many as total genius. He is well worth checking out in general.
Go grab the Ebow Zombies....
