Design and Build
The Acer M900 features a somewhat robust build, with dimensions of 119 x 62 x 17.1 mm and a weight of 188 grams. The phone has a substantial feel in the hand, fitting in with the trend of substantial business smartphones of its era. One of its standout design elements is the physical QWERTY keyboard, which slides out to enable faster and more accurate typing—essential for users who frequently send emails and messages. The black color gives it an understated, professional appearance.
