Pros: plugged the pc card into the slot and that was it. my vaio vgns360 with xp sp2 recognized it.. paired the sony bluetooth laser mouse.. fire and forget.

Cons: is not the zoom card; but i was hoping i could sync my iphone using my new bluetooth pc card but i learned that iphone bluetooth capabilities are limited. shame on apple.

Overall Review: do not install the software if you have xp sp2.. is not needed.
