I am a recent convert to the Mac, having played around briefly with a Mac Mini and liking the experience so much I tookthe plunge and bought myself a mac pro. Overall, I am very happy with the switch and the few Windows apps I still need run fine in Parallels for me. I do have a question on networking that I am not sure where I would find the answer for. The Mac Pro has two ethernet plugs in it. Is there any benifit to plugging two cables into it that run to the same router? Is OS X "smart" enough to use both? Or will the OS only use one of them? I know how this works in the Windows world but am still fairly ignorant on OS X.
