The video showcases and discusses the latest desktop computers and what features you can get with regards to screens and processor capabilities in the category. I've used a laptop for most of my photography and videography career. The idea of not being able to take the machine with me when I need to go has been my reason for not getting a desktop machine, and the work I do requires me to get up and go when a job arises.
However, having a capable desktop machine at home is something I have considered. Not needing to chimp down to your laptop on the table and being able to open several apps at any given time and having all the windows visible is something a 27" monitor will give you. Eye-level viewing is also ergonomically the best for your body too, espcially if you use a machine for a significant part of your day.
I use a Macbook Pro, but this doesn't mean I am not open to operating systems or PCs that can give you something more than what I currently have. The video also shows what Windows is doing with regards to providing tools for the creators in the creative industry, who depend on these machines and hardware to do their work. Although I don't think I'll switch to Windows soon, it's most certainly good to know what's going on with regards to PCs.
