Not certain that Apple is the dark side !
Both Maria and I have moved over almost totally. When we first setup our new office the IT purchase totalled
Apple TImeCapsule 3Tb (Broadband, WiFi, Backup, Server)
HP Colour Laser with WiFi and Apple Airprint
Apple TV on 42" LCD for meetings etc (WiFi)
Extension leads for 4 MacBookAirs/Pros
Chargers for iPhone and Droids (last a day, you have to be joking!)
Total installation time 30 mins.
The migrations is a little bumpy up front. If you are going to get the best out of it spend some time finding the additional User Interface benefits OS-X offers.
Learn to use the fullscreen applications and slide from side to side between apps
Learn 2-3-4 finger gestures up front
Learn the keyboard shortcuts
Youtube has a ton of instructional videos on the use of OS-X interface.
Welcome to the freedom.
