As many rumors are now starting to circulate about Snow Leopard's release date, should I see what new stuff is released in MacWorld, or satisfy my temptations and purchase a MacBook in time for the holidays? (I'd be willing to wait until January, but not so much as March or later for Snow Leopard. Any ideas of possible ship dates for Snow Leopard?) Thanks. additional details: No, I'm not brand new to the Apple community and I know they released the MacBook in October. The question is more about Snow Leopard's release date (general idea) as well other big releases at MacWorld.
