I use one win 10 pc built just a couple of days ago. It is an i5 12400 pc with a 24 inch monitor. Before I used a 14 inch acer laptop. Now every time I look at the monitor I feel like diving in it head first- it is too big.
I know how you feel, I believe monitors have gotten way too big. For a desktop, a 19 inch monitor is big enough and with laptops I would probably go for a 15 or 16 inch, because I noticed that 14 inch is sometimes a bit too small, especially when it comes to browsing.
Revision: An iMac, a MacBook Air, two Chromebooks, a Juno laptop (custom build), a Lenovo G500 laptop (both running Ubuntu). Several tablets (Android, Kindle). I had others but now they're toast.
But you cannot deny the joy and simple pleasure you get from crouching over when using a 14 inch. I miss the neck and back pain. Sometimes I will crouch over to see the bottom of the monitor out of habit.
The problem is that many websites use fixed menu's on top, so even if you scroll down they stay visible, which means there is less visible screen space. You can somewhat fix this by switching to higher resolutions (or basically zooming out) but this makes things too small. I use my laptop only at home, so I may as well buy a 16 or even 17 inch laptop, eventhough smaller laptops look more sexy.
One with Windows, though I used to boot it with Linux sometimes. I also have an archaic Android internet tablet that surprisingly still works.
