I travel some and have Windows XP on my work computer while my wife has MBP running Leopard. I am thinking of buying a MB alum. Do we have to have two separate Mobile Me accounts (or a family pack) to use the Back to Mac feature for me to control her computer? What is your experience with this feature? I would like to help fix her problems when she has them and to be able to access some files (like budget software) while I am on the road. Are there other programs that work for this purpose? Thanks.
