My venture outside of MacBooks included a Dell XPS. Supposed to be their high end, and that year's model was well reviewed by multiple sources.... yet I returned it after like a week. The fan would not only run far too often but the sound it made was also atrocious. I have no clue if mine was defective or if all the reviewers are deaf to high frequencies. And the body was so flimsy that I would grab the corner of the laptop to move it and end up triggering a mouse click.
