We have an AlphaSmart Neo now, thanks to Bronwyn! Her son was moving up to a newer model with more bells and whistles, and she generously mailed this out to us, complete with instruction book, cables and a lot of good wishes that someday Woodjie will use this, too. I don't know that the AlphaSmart will improve Emperor's spelling (it's already pretty good), but it will CERTAINLY assist me in grading it. He frequently gets things marked incorrect as if Mom can't read it, it isn't right.
I will try to balance my understanding of Emperor's motor difficulties with the simple fact that we do need to work on his handwriting. I have myself a feeling after these first few uses that Emperor will want to have his AlphaSmart wherever he goes. He is very attached to it already.
