The only other device the Samsung Magnet a257 can compare to on AT&T’s lineup in terms of design and form factor is the Pantech Slate. Both are classified as entry level messaging devices, except that the Magnet gets some kudos in design. It’s similar to the Slate because of its QWERTY keyboard, low weight (3.09 oz), and thin profile (0.47”). The orange plastic material is appealing to the eyes with the back cover having a patterned design. The materials feels well constructed and does not seem as cheap as the Slate. Holding it in your hand feels natural thanks to the back cover having a soft matte feel created by the patterned design. Its very light weight and does not add any bulge if you place it in your pocket.
