How to bring MAC OS into Windows Office Environment

Hi guys

I have a client that wants to replace her current Dell laptop (with docking station) with a Macbook (and docking station) in her office. All the other PC’s on the network are Dell and are Windows based.

I have never attempted this and would just like some more information and suggestions on how to go about doing this.

i.e – which Macbook and docking station you suggest,additional software needed for her work to continue as normal,any compatibility issues I should be aware of.

Thanks in advance.
