I would cry tears of joy to get a laptop with mouse buttons. Trackpad gestures are a gimmick and so much harder to user than buttons. Apple did it to be "bold" and everyone copied them.
Apple has only ever shipped single-button mice with their computers, so turning the whole trackpad into that button on their laptops was a pretty simple evolution. Gestures came much later.
This is one of the reasons I still enjoy using my old XPS. The buttons are great: nice deep solid clicks. Even doing stuff like dragging windows around is so much better than on a touchpad-only design. (I've used Macbooks with the old "hinge" style touchpad, and they're even worse than using a double-tap-and-drag gesture, just because of the force needed to keep the button pressed.)
Given the number of people these days who don't even own a desktop, I don't understand why mouse buttons aren't the standard. With the XPS I can even play casual games while sitting on the couch. No need to move to a desk and dig a corded mouse of the drawer!
I moved from Macbook to a ThinkPad (trackpoint+trackpad+mouse buttons+trackpad buttons).
I never used gestures. But I seriously miss inertia scrolling. You never realize how much a pain in the ass it is scrolling web pages until you don't have it. Firefox has it, but you have to turn on an environment variable to get it and it feels a bit weird to me. Chrome does not have it all on Linux. And the way they are implementing it means that every app has to reimplement inertia scrolling on its own. Sigh. At least you can hold down the middle mouse and use the trackpoint to swiftly scroll.
Maybe I'm mistaken, but this is just when you scroll, release your fingers, and it slows to a stop instead of stopping instantly, right? I have that out of the box here on Linux. Firefox + X + touchpad with the synaptics driver.
I had thought this was what "Use smooth scrolling" did it in the Firefox preferences.
Edit: I also just checked and I have this in my terminal (Konsole), text editor (KWrite), and PDF viewer (Okular) so this is at the very least not a Firefox only thing. It feels exactly the same in each application. I bet it's a feature of the touchpad driver.
