While they are similar in some ways, they are not as similar as the article makes them out to be. From images I found elsewhere, the iMac seems to have its components behind the screen, and a very thin stand, while the Spectre One seems to have its components in its thick stand, while its screen is thinner. I think the article is misleading by not showing that, which to me makes them completely different designs. As for the keyboard and trackpad, of course they're going to try to make them as small as possible.
