Design and Build
The O2 Cosmo features a compact, robust design typical of its time, with dimensions of 111 x 62 x 13 mm. Weighing 130 grams, it strikes a balance between being sturdy and portable. The use of a QWERTY keyboard is a hallmark of productivity-focused devices from this period, appealing particularly to those who needed efficient text entry for emails and documents without relying entirely on touch-based input. The build feels solid in hand, although the aesthetics might seem dated against today’s sleek, minimalist devices. The keyboard is well laid out despite the relatively confined space, making it a practical solution for business professionals on the go.
