How noisy are keyboards for Sony PDAs?

[DJ Zaki]

I'd like to buy a keyboard eventually for my PEG-SJ20, but I don't want to get a keyboard that is going to do as much noise as a normal keyboard. It'd be perfect to use in class for lectures, but I can't get one if it's going to make a hell lot of noise!

I bought and frequently use a Stowaway keyboard for my Clie, and I'd have to say that it's very quiet, not noisy at all. I use mine in meetings all the time. You shouldn't have to worry if you go with one and need to use it in a class-lecture style environment.
