Eller asked for reasons he could present to the board that showed the advantages of a dual platform approach. MacCentral readers sent him LOTS of information, which Eller kindly shared with us. But he says he doesn't need any more info. Throughout the DNER, Macs and Windows are interspersed. The DNER has 'standardized' on Microsoft Office rather than a hardware platform, and this allows us to easily share files between the two operating systems.
Difficulties are minimum, and complaints virtually non-existent.
The DNER's Computing Center provides maintenance on the Windows machines. Within my office, we'll be networking the Macs and Windows machines within the next couple of weeks, using Ethernet. The ones who benefit the most from single-platform Windows work groups are the service contract providers, not the users. It can coexist in a PC world. Mac clients can share PC data and MAC servers can easily share out to PC clients.
