Re: Not a universal view
This comment is spot on, and the article is written from the viewpoint of the "power" (or is that "nerd?") users who actually do employ multiple laptop ports at once, and carry around the mess of cables, mains adapters, and USB peripherals that reflect that usage – but not from the vantage point of the target audience.
You've probably never seen the target demographic, US college students, in their native environments. They charge their laptops overnight, and don't even take their chargers to class/library with them. They use a multi-gesture touchpad, not a fussy and old-fashioned pointing device like a mouse, and they never, ever bring USB cables with them. (Ask campus tech out if you don't believe me.) They pop their laptops in rucksacks, and that's it. And a startling percentage of them already have MacBook Airs, so this is aimed at the same demographic.
