As mentioned in an eariler article (see below), the supplied Palm Centro stylus is flat out terrible. Today I received the steel-shafted replacements - they are perfect, just what Palm should have put into the phone in the first place. They are still hard to hold because they are tiny, but at least they don't flop around.
See the 3-pack at Seidio Online; shipping out of Houston was prompt via first class mail.
Singles are also available but I recommend anticipating losing a stylus, especially these tiny ones. Trying to buy an accessory for a cell phone a year later can be tough - hedge.
The stylus is no minor matter. Because of the relatively small screen, the stylus is required for almost everything other than dialing the phone.
