I just got a new Dell Precision 7740. I had a Dell Precision M4600 for about 7 years before this one and it handled rough environments just fine. The new one has 3 standard USB ports and 2 USB-c thunderbolt ports, HDMI and DisplayPort, Ethernet Port, and headphone out.
I didn't want Win10, yet, so I ordered it with Ubuntu and run everything in VMs (i even turned my old laptop into a VM so I wouldn't lose anything). 64GB ram, i7 (6 cores), 256gb OS drive, 1TB 2nd for VMs. I paid $2400. If I get another 7 years from it, its less than $10/week.
