Mobile workstation is the way to go, IMO… Especially if it’s work related, has colour reproduction accuracy (dE) needs (beyond just the sRGB space), requires high performance encoding support / dGPU (e.g. h265)…with high throughput, and hardware expansion capabilities (e.g. THICK ones can go up to 4 DIMMS, with 3 m.2 NVMe slots…beyond thin&light category).
There’s also a question of how much processing capability you need on-the-go / built-in, and how much you can externalise (eGPU to distributed to desktops/network)…
For example, a low end mobile workstation, with i7-1280p, 32GB RAM, 1TB SSD, nVidia T550 4GB, and WQUXGA HDR 400 500nits display is $2232 CAD:
Or something beefier (just a tad over 2,344 quid):
(Personally, waiting for P16 to go on sale)
