In the graphics business, Macs rule! While Macs and PC's are "supposed" to talk to each other, in some instances, they don't. Font's and column lengths change, making for real problems in the publishing business.
Here, we use Macs for all publishing projects and PC's for all data management (research analysis) projects.
Good luck. Rightr brainers (creatives-abstract thinkers) love Macs.
