Have just bought an Asus eee Pad,bought 2 styli at the same time. The styli are designed for capacitive screens,would they cause problems if they were used on a Sat Nav that has a resistive screen? Intend on using the onscreen keyboard for typing,to avoid cleaning finger marks away continuously,are capacitive gloves worthwhile? Have seen a pair for £9.99 where all the fingers and thumb have conductive material in them rather than just two or three. Thanks in advance.
