I am Precision 7 owner. With Skylake you still have 4 SODIMM slots and the new ones are a little lighter than the older ones, so you can have 64 GB RAM, a proper quad-core i7 (or Xeon), and discrete, removable graphics - the video card is on a daughter card that can be swapped out. Mine has an M.2 SSD and a big hard disk in it, a real GTX 960 eGPU via Thunderbolt 3, and only 32 GB RAM for now. Running Linux it has tons of overhead for multiple VMs (my Win10 VM has 8GB RAM), and lots of processing power. Unlike most laptops the Precision 7x series also is built to run flat out without throttling under load. Yes, it weighs like 8 lbs, and I don't think the new "carbon fiber" ones feel as durable as the older tan aluminum ones, but it's definitely a worthy replacement for a desktop. I just take a netbook with me most of the time when I need portability, but it's great when I know I need horsepower somewhere other than my own office.
