While Macs haven't had any decent adoption from the gaming community, the music and office communities are all over it. And the DAW you use doesn't matter so much as it follows the proper conventions for plugins to work (they all do). In terms of home office functionality, you can get all of the same Microsoft Office programs but the native Mac ones run a lot better and get the same job done (like Numbers replacing Excel, Pages replacing Word, etc).
I've been on a Mac for about a decade now and haven't looked back. In terms of workflow, it's a much faster and intuitive experience. In terms of viruses and all that other crap, I've not had any virus protection the whole time and it's never been an issue. The operating system is isolated from user files anyways. It's all in all an entirely more well-thought out system.
The only issue is you pay the "apple tax," meaning the hardware is more expensive than it should be, but what you're really getting is access to the far superior software.
