I ordered a stylus thinking it would make using iannotate more pleasant. I got the BoxWave Capacitive iPad Stylus with the large rubber tip, but it really sucks. It seems way inaccurate when I try to write with it and it makes a squeaking sound. I have a feeling the squeaky sound is due to the plastic screen cover I put on the device. Do any of you use a stylus and is there one that you'd recommend?
