I find the number of posts denigrating the OP for the thread and speaking as to why he decided to purchase a dell instead of a new Mac kind of telling about the Mac community and why so many people think of us as elitist. Someone leaves the "club" and it's "kick rocks, I don't even know you anymore". I wonder just how many of those same users would welcome him with open arms if the purchase was in the opposite direction?
After all of the problems with my 2016 MacBook Pro; battery life, sleep/wake, random shutdowns, more crashes than one can imagine, file corruption, etc... and NO help from Apple whatsoever, I was tempted to buy the XPS 15, and I have owned one before, so I know of the issues it can have. None of the problems I had with mine came close to the problems I experienced with my 2016 Touch Bar MbP. In fact, the only thing that kept me with the Mac was the deal that I ended up getting on a 2015 15" rMPB.
I've been an Apple user since '96, but I am far from a brand loyalist when it comes to loss of production time. And as Sigma mentioned above, with Adobe CC being cross platform, it wouldn't be too difficult to jump. Had the Dell been Cheaper than 2k for the config I wanted, I probably would have. We have already replaced our iPad Pro(s) with the Microsoft Surface(s), just for the ability to hand it over to a client and let them see changes to their layouts in realtime in Illustrator.
