I have long been a champion of practically and simplicity. In the past this meant that I would recommend most companies use PCs for their workstations and Linux and other open-source products for their servers. Well, the times are changing.
I ditched my PC in 2006 when Apple starting making computers with the Intel chip. In the roughly three years I've used my Mac I've found that I could always find the software I needed to perform my tasks. I've also found that it is really easy to run windows on a Mac for those occasions when I need to test something out (like to make sure my business website looks normal in Internet Explorer). I can get all my work done on a Mac, but one of the greatest benefits to my Mac is how stable and easy to use it is. It never locks up, I don't get all kinds of unwanted software running on it and its always seems to run pretty quickly.
Now in the past these were great reasons for why a single user should go with a Mac, but for a business, where many computers need to work together, adding a Mac to the mix was asking for problems. But now I feel like we have reached a point where Macs can work well on corporate networks.
Google applications is one of the best email and calendar solutions for small businesses, and guess what? It works just as well on a Mac as on a PC. I also use many open-source software products, like email marketing and customer relationship management that all run through a web interface. These work just as well on a Mac as on a PC. Finally with Samba, the open-source file server, you can access shared files with your Mac just like you would on a PC.
So, if you are looking at purchasing a new computer, there might be advantages to considering an Apple product. It isn't the best fit for all offices, but it might just save you or your employees from facing that ubiquitous blue screen of death again.
