I currently have a 2007 Alu iMac C2D (2.4) with 4 gigs of ram that is crawling. I was hoping for a "mini" MacPro to be announced at WWDC but it wasn't. So now I've turned my attention to the MBPR. While I'm happy to have the portability the computer will primarily be a desktop replacement. I have a few questions: 1. The battery. I know many recommend pulling out the battery in laptops when being used as a desktop. Is there a way to prolong the battery life? 2. I will need to get the ethernet to TB dongle so I can use this at home. Is there a way to hook up 2 monitors to the computer AND have ethernet?
