Qimo is great it's just very limited. My kids have had it since they were 3 and the only thing they still play is tux.
unfortunately, when it comes to fun and educational for young kids there is infinitely more stuff for windows. that's why I thought wine would be a big plus.
Qimo is just Ubuntu by the way. With the kids dock and some very old games. I just think someone with talent could do better and like I said it's a niche that would be noticed in the linux world.
another good alternative would be something aimed at the elderly. There is a neat UI called eldy
but the linux version supposedly made for mint (again just ubuntu customized) sucks.
