Ultimately, I want a mouse that will so radically and miraculously rearrange my life that it is no longer necessary to spend so much time every single day in front of the same screens for hours on end. Short of that I could do with one that fits to my palm better. I recently picked up a Logitech g502 hero, there's a whole subreddit about that mouse I guess. Before that I had a Mionix Naos 8200, which was also quite good.
