Catering to largely business clientele, Nextel's past handset lineup has consisted mostly of bulky candy bar-style phones with monochrome screens and a basic, albeitsolid, design. But as Nextel's Direct Connect Push To Talk (PTT) walkie-talkie service now faces competition from Sprint PCS, Verizon, and Alltel, the carrier is supporting smaller, more stylish Motorola models. While not the company's first handset with a color screen--that was the i95cl--the Nextel i730 has a streamlinedflip design.
