...it's just that Microsoft's initial implementation was poor IMHO. The whole concept is great. At my work, we have available a tremendous amount of online training through a combination of video and PDF, etc. The thing is that what Microsoft didn't study, or perhaps did but didn't understand is that since childhood, kids are raised to see cartoon charactors as, for the most part, a little retarded. So anyone seen using a cartoon charactor to teach them concepts and usage of a software program will be seen as being retarded.
I bet that if they had done a proper, professional, and serious implentation, that it might have gone better for them.
