We use Dell Precisions at work and just a fair warning: Dell is completely clueless when it comes to software/firmware. We had stability issues for months with our laptops, which were fixed for the most part by firmware updates. A good amount of the laptops never came round, even though they are identical models and now have the same firmware running on them.

I have considered BYOD a Gigabyte Aero. I will personally never purchase a Dell for myself.
