I actually play on a laptop full time - I own a small foldable table with a built in mousepad and that's it. That's my "battlestation". All of my computers for the last eight years have been laptops. I was recently able to afford this one two years ago and it was worth all $1,300.
My laptop, while fairly powerful, has a couple of limitations. It has some positives, like it's easy to take with me and it doesn't shut off when the power goes out, but it also has negatives.
Along with needing a cooling pad and costing more to fix when it breaks, it has a very small screen. My laptop has a 14 inch screen, which translates to not having a lot of space on for a fancy UI. I'm a function over fashion person to begin with, though I do feel a tinge of envy when I sit down at someone's desktop and they have all the space in the world to do whatever they'd like with their UI. Not all of my mod choices are related to reducing memory usage or making the most out of my tiny screen, but here are a few of my favorites.
