Good to see this item software finally come across to the Apple platform. My only complaint is cost - USD 230 to 350 depending on the version. However in a corporate environment the price may not be a issue. For more information goto: www.mindjet.com/us/
A alternative and one that has been around for a while is Inspiration. Retails for USD69. Plus they also have a palm version USD 30. The two items bundled together will set you back USD90. Details at: www.inspiration.com
So for Mind mappers and Apple users another great day.
