Hey Lloyd, I recently purchased my XPS15 9550 after my HP laptop faded out on me. I just received my TB16-240W Dell dock today. I was doing all of my homework and internet activity on my laptop (which I love). After completing the BIOS update to the laptop, connected the TB16, then went to Dell.com/support/downloads to get the updated drivers for the docking station. Now connected to everything at home including the 24" monitor...so much easier to work on multiple projects / screens when you can see them. I know they are offering some 10 - 15% discounts thru may 1st if you haven't ordered your dock yet.

I don't think you will regret the investment.

Good luck to you.

Michael
