Damn, I just broke my stylus (350) too.
And I was aware about it's weak construction!
Seems that it is a Sony fail in design
Is there any chance to make Sony produce more durable stylus for our reader?
Can't say that I used it very often, but sometimes it was very handy. And besides... this empty hole looks ugly, like a dented tooth.
Did anybody master to find replacement stilus for a reasonable price?
