It might seem a stupid question and it’s probably why I haven’t found anything on the internet but it actually makes some sense if you see my point from a gaming perspective.
Although a Laptop is supposed to have a touchpad because it is supposed to be portable and used without connecting another mouse to it or any other hardware when you look at it from gaming purposes no one uses the touchpad. Also, if you are used to playing on a PC and you use the WASD keys for movement your hand rests nicely on the desk because your wrist rests lower than your fingers. However, on a laptop, you are forced to rest your wrist on the laptop itself which is on the same level as the keyboard and makes it uncomfortable for the hand. And it is all because of the touchpad.
Another thing is that, if the touchpad gets removed, laptop keyboards can get bigger and make it more comfortable for gamers as a lot of keyboards on laptops are quite small.
Now a lot of you may still laugh at me and say I’m dumb, because why not just build a PC then? Well, again, it is a gaming laptop I am talking about, which you can still carry around easily unlike a PC and you only need to include a mouse in your bag, which the majority does anyways today.
Also, I would like to know why this would not work, like if I am missing something in the design behind laptops as I am in no means an expert in this area. It’s just an idea that I believe with the latest technology development would make sense but is still not out there.
