It's insane that they don't support a 17" option still. Those machines were beasts. If I could have afforded to spend twice the money on a laptop at the time, I would have gotten one - I still probably should have with the number of HPs and Dells and Asuss I've gone through since.
The screen size wasn't the only motivation. I like my laptop to be a portable server. This thing has 3 HD (2 NVMe & 1 SSD), up to 64GB / ram, 4 USB 3.0 ports, 1 USB-C, 1 Mini-Display/Thunderbolt, 1 HDMI, SD card slot, ethernet port, finger print scanner and a smart card slot.
Plus the battery is replaceable.
I love my beast of a laptop with all the interchangeable parts.
I understand that, I went with a T470P which is an absurdly powerful little machine, i7-7700HQ, 32GB RAM, NVMe storage, no thunderbolt but I had no need for it also has HDMI, DisplayPort, Ethernet port, Fingerprint reader.
Happy with it for what I paid (lot of machine for the money).
