I would think so! Some people have special computing needs that make certain hardware more suited to them, or offering the features that allow them to be productive.
Instead of setting standard hardware and hoping that results in productivity, why not set standard productivity and let people use whatever hardware they need to reach that level of excellence you expect?
Personally I have made use of iOS, Android, Windows, Mac, and Linux operating systems to get work done, I've used Macbooks, iMacs, windows laptops, tablets and phones.
I can't imagine how I could have output so much work if I was only working from a hardware setup somebody else had chosen in advance for me (somebody not me, and not solving the problems I work on).
I guess the bigger question is: do you care more about getting work done, or cute matching laptops. For me, the choice is: getting work done.
