I love my Sena case.
Ray - I don't think the desktops have a new operating system. You may be referring to iLife 08, a updated suite of multi-media applications.
More info on this can be found by clicking this link. I believe the current operating system OS X/Tiger is being updated via the release of OS X/Leopard in October.
More info on Leopard can be found by clicking this link. I can not wait until the upgrade becomes available. :D
Hope that helps.
