Let me just throw this idea out and see what you guys think:
I am very sure that typing has caused my handwriting to deteriorate.
See, when I was in school, my English handwriting was often praised. Teachers liked it for being strong, having a personality, yet very easy to read and understand.
My Chinese handwriting, heh, was severely criticized. It was readable but totally uncultured and lacking in refinement. (EG absolutely nothing like tp4's Chinese handwriting on the first page of this thread. I'd say TP's Chinese handwriting looks like a real Chinese person in some Jiangnan teahouse and mine like some Taoist hermit living on a mountain.)
But after two decades of typing....
My English handwriting is awful. Virtually like Chicken scratches. I wince whenever I write something. I can't even write as fast as I could when I was in school and rushing to churn out essays with maximum word count in the time limit.
But since I still hand write more Chinese than I type it, my Chinese handwriting has marginally improved. It actually looks more mature. And I can still write at the same speed, which is much faster than I can type in Chinese. (Sigh, I really show my age here!)
It will be interesting to hear what you people have to say about this.
