If you're looking for the Grand Poobah of smartphones, look no further than Nokia's new $1,099 E90 Communicator. As opposed to Nokia's multimedia-focused N-series, the E-series focuses on messaging. In Nokia-speak, that basically means these devices have QWERTY keyboards. The reality is that this unit is quite capable as a multimedia device, just as the company's N-series phones are also excellent e-mail handlers, despite their numeric-only keypads. The unlocked E90 is a much-improved follow-up to the clumsy 9300 and 9500 Communicators. Along with stellar voice quality, the E90 includes dual screens, dual keyboards, Wi-Fi, Bluetooth 2.0, GPS, plus an entire suite of applications that would cost significantly more with other smartphones. Any way you slice it, this is a precision-engineered instrument for those who can spare more than a grand and have extra-large pockets.
