Hi,
Let me first of all say that I like the concept of skritter a lot. It is by far not as dull as using flash cards and you actually learn to write characters as well, not only to recognise.
Here my question: I understand that the mouse is meant to be the main input device. However it requires a lot of clicks for each character and after using it a while it becomes quite tiresome. For the same reason it is not very practical to us a laptop's touchpad.
In China you can get these small tablet devices that you connect via usb. You can then enter characters by writing on them with a pda style pen. Have you tried if this works with skritter? These things cost way less than RMB 100 here.
I would find this quite interesting since it is a more natural way of writing than using a mouse and also much faster, i.e. I could go through characters quite a bit faster than using a mouse.
Thanks for your feedback.
