I have been trying to use my Transformer Mini to do more note taking to help reduce the number of notebooks I carry around, and to allow me to share my notes over multiple computers / phones. My problem is thought the ASUS pens works fine for while, I'm finding that if the mini goes to sleep, or if I don't write anything for a short period the pen no longer works. Removing the battery and re-installing (rebooting the pen) seem to work but it does get a little old. I thought I read that the Surface pen worked with these. Does anyone know if they stay connected better than the ASUS one?
