An anonymous reader writes: Earlier today, HP announced the Spectre 13, the world's thinnest laptop. One of the subtle changes HP is making with its recent global brand offensive is to its logo. HP has decided to go with a minimalist design consisting of four slashes making up the "HP" brand name. Previously, "Hewlett-Packard" was written out in full on last year's Spectre x360. HP says it will be using the minimalist logo solely on its premium laptops. Even though the logo has received a makeover, it's not exactly new. This very same mark first surfaced online in a 2011 brand redesign study released by Moving Brands, who HP had hired to develop a new logo and brand identity.
