InteracTV or Learn Through Music?

[westgre]

DD has outgrown her LeapFrog Little Touch leap pad, so I was going to buy a replacement gift for Christmas. I think she's Leap Padded out, so I was looking at either the Learn Through Music or the InteracTV. I like that the Learn Through Music is not attached to the TV, mainly for in the car use, but also to not tie up the TV all the time. But the InteracTV looks a little more educational. Does anyone have reviews of either of these? BTW, DD will be 3 years old on Dec. 30.
Thanks!
