CeBIT America 2003
Siemens had a table at the Digital Experience press event the night before the show, where one of the first working units of the SX1 was on display. The SX1 is one of the first non-Nokia phones to use Nokia's Series 60 smartphone platform, which is powered by a Symbian OS core. On the hardware side, the SX1 is considerably smaller than the Series 60 devices from Nokia so far, while still packing in features such as a large display, MMC card slot, and camera. On the software side, the SX1 sports a sleek interface, and number of extra applications not included on Nokia models.
The display is quite nice - comparable to the display on a Nokia 3650, although with 65,000 colors, compared to the Nokia's 4,096. The odd numeric keypad, however, is quite cumbersome, even when using two hands. Keypad aside, the phone has a great feel to it. In photos, it looks slightly smaller than the 3650, but in real life, it feels much smaller.
