I suddenly found myself carrying a 17” Sony Vaio to work in CAD and a 13” white Macbook to do everything else on. Then, at the end of 2007, I bought a white Macbook on clearance from a reseller store. I built PC’s, ran out to buy Vista when it was released, and used Windows Media Center to run my entire home entertainment system. The same way roads are not specific to one car brand, each user should be able to choose an operating system that they prefer (for one reason or another) to get their work done. Everyone has their bias and at the end of the day it comes down to personal preference.
