A word about Palm Desktops:
Sony version is very stripped down, you can use a palm desktop version but you need the drivers to get it to work. You could put it onto a memory card, use a card reader/or use data import and point the installation question towards where you have the installation driver located. Ask more questions here if you are still confused, but please show that you are trying at least, and give info on type of computer etc.
