I'm about to purchase a mac pro and was wondering if it comes with wireless connection. I noticed in the configure page, it gives me the wireless option to purchase AirPort Extreme. I read the description but I didn't understand its features. Can someone explain it more clearly? Also, as I was customizing the Mac Pro, I planned to purchase the Adobe Suite CS3. Is it installed in Mac Pro once I receive it in the mail or will it come in an Adobe Suite box so I can use it in other comps? Please advise. Thanks!
