I dont think itd be much better but it has a small footprint and is more usable at that size than a trackpad. I think those are good qualities to have for a small portable device like this. I like my steam deck but I dont personally use the trackpads often and almost never the one on the left so one small nipple would be amazing for me. I used it a lot on my old lenovos.
I actually went from a 7 pro to a 9 pro, and while Idk if its small enough for you it is a massive change in usability for me. I disliked the 7 it was usable but annoying at times to reach stuff I almost never have that issue with the 9 pro.
