Both my parents own there own companies and use mac products in there office. they are Tax accountants cpa-MBA. if your looking for viable protection and the least downtime. because Microsoft Office is on the mac. the only thing that i would see would be a bit strenuous would be that you would have to open such programs as bootcamp or parallels which my parents use when they need ot use windows only tax software. but if you don't mind the flip flopping if you use programs that are windows only or your company uses windows only then i would be a bit skeptical. but if your looking for a secure safe and a great computer experience i would recommend a mac. I believe with valve building its source engine and releasing steam for the mac it will spark life back to the mac development. so its all about choices and what software you use and what environment you want to use the software. hands down though for anything dealing with personnel information i would recommend a mac because you have a less of a risk of worrying about your keys being logged or vital information being streamed or uploaded by all sorts of bad stuff that plagues Windows OS systems. i would also recommend linux but its kinda for nerds lol i dont even use it! but its just as good as mac osx.
