IMHO there are many things to dislike about 'modern' GUIs!
Back when Windows was a relatively new concept common sense things like making buttons stand out and using colour and borders to group and organize features. These things have pretty much gone out the window. Everything is a flat homogeneous dark scene.

If I'm on a desktop, then I use the mousewheel for incremental scrolling and home/end/page/up/down for faster scrolling.
If you have a long page and your looking for something "about this far down the page", there should be a TOC or a map.
On touch interfaces, it's just the side of the screen or standard scroll.
At this point, for me, a scroll bar is more an read only position indicator than an actual navigation tool.
Interested to see if I'm in a minority here.
I love my little HP plastic laptop. It's a plastic toy I got for $85, including a Windows 10 Pro license, and I just toss it into my bag when I want to go somewhere. Perfectly adequate for text editing. Yesterday I had Visual Studio Code, web browser with 10 tabs, Ubuntu 19.10 via WSL, and Docker desktop all shambling along. I felt like Jason Bourne driving an attack Lada.
My other Win10 device is a ThinkPad x230. Its touchpad is also limited, but has three real hardware buttons.
Mostly I use similar aged MacBook Pro or iMac with Magic Touchpad. Totally different level of quality, no comparison really.
I always wondered why pro Windows laptop users in my family only used extra USB mouse devices. Ugh. I have yet to experience a mass market Windows laptop trackpad that most people would be able to use full time.
It comes in quite useful when I need to move over a lot of space to find what I'm after. I'd be using the wheel on my mouse for quite some time otherwise.
Yes, all the time.
Seriously annoying.
