At work, I'm trying to convince our IT staff to purchase 17" MBP's to replace our G5 towers. We do a lot of production/prepress work in our department, but a lot of design/layout as well. With processor speeds at the level they are now, and the 17" being able to go to 3GB of RAM, the laptops are becoming closer and closer the desktop's equal. IT is looking at the mac pro towers and need a gentle push in the laptop direction. As the Creative department, we are the only ones without laptops (everyone else has Dulls). There is no wireless network (yet), but we're working on that as well. All of the conference rooms are wired, so we can access the network that way. The costs are quite similar for the boxes I've spec'd out, so financing isn't the issue. The other AD has voiced his support of the switch to laptops, but I need more info/ammo to support my argument when I show up to present my case to IT. Any help?
