Therefor the total market for these SIMMS is considerably larger. As for using them in a Mac, I would have thought that it was fine, but I do remember a recent posting saying that it wasn't really safe, as there is then a line or 2 that are not tied down (or was it tied high) these supposedly cause potential noise/heat problems. I really dont know how true this is (details anyone who knows?) but it would seem to be supported by one of the rumored design details of the fall version of the cx, that it is specifiacally designed to accept either type of SIMM.
