Stop anthropomorphising your computer. If your RAM, disk, and CPU let certain software perform as fast as necessary, any "bloat" you are asribing to things is purely psychological, philosophical, or due to something else like poor UI design. Traditionally, "bloat" means that there is too much memory-resident tools or features such that their cumulative effect, while negligable in separation, becomes daunting for your machine to handle, resulting in a sluggish user experience.

So, "bloat" is relative to your machine. What's "bloated" today is not going to be bloated 5-10 years from now, and vice versa. If this isn't what you're talking about, you're using the wrong word.
