With a slimmer profile and a dramatic bronze finish, the Nextel i830 looks very different from most Nextel phones, but packs the same walkie-talkie feature (officially named Push-to-Talk, or PTT) that makes these phones popular with business users. You'll either love or hate the metallic copper-tone case, but for us it is a welcome break from the generic silver or gray phones that everyone seems to have. (A silver version is also available, for the more timid.) Although by no means ultra-light, the i830 weighs just 3.6 ounces and measures 3.3 by 1.8 by 0.8 inches, making it the lightest Nextel phone on the market.
