I coach my clients on the best strategy for acquiring and maintaining their hardware.
I personally use both a PC and a MAC. They each have their strengths and weaknesses. I have an android tablet, but I use an iPhone5. I love Apple products, but some people will do just fine with a Windows machine and Android mobile devices.
The great thing about today's marketplace is that there is an app for everything that you can imagine both on IOS (Apple) and Android.
I offer suggestions for making the most of the hardware you currently have and developing a strategy for the future that will be the most cost effective and easiest solution for your business.
