I currently have a 2008 K2 Moment and it was a great board to learn on however it is truely a beginner board. I out grew it in 2 seasons easily skill wise. So it will all depend on wether you want a board that will last a little longer or if you're willing to upgrade once her skills progress.
The moment has great turn initiation and isn't too bad in icy conditions if the edges aren't too dull. I loved riding it on hard pack and in moguls. Because it's such a light board, for me anyway, it was not fun to ride in heavy snow or on steeps.
