Thought some of you might get something out of that link. It compares all the recently released models of dictionaries for the Japanese learner.. Several makers are reviewed, but the main focus is on the two top contenders, sharp and Canon.. But seiko, Casio and a few others are mentioned.
I am probably going to get the Canon G50. Because it's what I need.
This is what sets it apart from ketai and PDA based dictionaries:
The second new function was not announced, or at least I didn't here about it until I bought the G50. When you are looking at a kanji in the Kanjigen dictionary, you can push the Spelling button and it will animate the drawing of the kanji displaying not only the stroke order, but also the direction of the strokes. I believe it will do this for 2,600 of the kanji listed.
I mean, getting the stroke order is very helpful when learning Japanese. Plus it is the top of the line model, with the most entries of any other product.
