Title: Find an Alternative
Review: I've been in touch with Nuance to ask about compatibilty. The reviewer above is right that ViaVoice doesn't work with later versions of Mac OS 10.3/Panther. Neither does it work with any version of 10.4/Tiger. I was told that Nuance is working on a Tiger-compatible upgrade, but that no release date for the upgrade could be given-- not even an approximate one. Unless you're willing to postpone upgrades of your OS indefinitely, order iListen instead. It isn't Naturally Speaking, but at least it runs on the current Mac OS.
