Hi there, Been a pc user all my life, have just ordered one of the new Macbook Pros and although I work in I.T., I have 0% hands-on experience with Macs, and little experience with laptops in recent years. For the Aussie wireless ISP called Unwired who I'm about to sign-up with, they have two different modems than can be used - the external "Wireless Modem" and the internal (manually inserted) "Wireless Card". I'd rather not use the Wireless Modem as it's so big and clunky compared to the Wireless Card. I'm wondering if anyone who has the Unwired Wireless Card can tell me if using that takes up a side plug-in slot that would otherwise be used for some kind of Apple wireless card (that might be used for peripherals or networking, etc.) that comes with the Macbook Pro itself? Or is all the wireless functionality on a Macbook Pro completely in-built already? Cheers, Terry.
