ok, i'm a new mac user (3 months) and i really don't know how to make the switch from panther to Tiger.........how should i do this when Tiger comes out?....should i install Tiger over Panther...or is there such thing as "uninstall Panther" ??? can someone address me on this matter......'cause i'm interested in purchasing Tiger when it comes out. Another thing: Is it reliable to upgrade to the first TIGER??? or should i wait a little bit after its release?
