Hi im studying Architecture and have a 12in iBook G4 old but good. Im going to be upgrading soon and would like to know if a 17 macbook pro would be better than the 15in macbook pro. Ill be on the bus to and from uni and will not have far to walk when im at uni. but what I want to know is this. Should I wait till nov to get one when leopard comes out when I hope they will do an update. ill be using autocad so I need an intel laptop thats one reason why im upgrading.any info would be great thanks.
