We asked professionals if they wanted Apple’s desktop, and they all said no.
This. Good enterprises offer both options. I think people are starting to realize that its best to let people pick the tool that works best for them in this circumstance. Also, equivalent Dells (I have mainly worked at Dell shops lately) are actually more expensive than a MacBook Pro.
Another thing is that enterprise tools lock down Macs a lot less in my experience. This usually pushes people in the direction of Mac when you don’t have to go through an approval process to install an app or package you want to test.
