I'm curious about this too, since I am intending to get DD one for her first birthday. I just don't know if it's really as super awesome as it looks, or just a glorified baby mechanical bull.
DS just got the pony (new version) for xmas but we haven't tried it yet. We bought our friend's DS the zebra and DS has tried it a few times at their house. My biggest complaint is that his feet don't reach down yet for him to be able to bounce. He does enjoy it when I bounce him though. Otherwise it's a cute toy.
Chase got this for Christmas. I think he's too young for it right now, but maybe by the time he's 1 it will be better. If I were spending the money, I'd probably buy something different. We'll see in three months though!
