Why have a separate notebook and mobile phone when one device can do it all? Well, almost. The Nokia E90 Communicator is the latest in the company’s line of fold-open smartphones with QWERTY keyboards and comes with a wealth of connectivity options, including both quadband GSM and WCDMA (with 3G and HSDPA for high-speed internet on the go), 802.11b/g WiFi for connection to hotspots as well as a proper HTML web browser. No matter where you are, you can probably stay connected with the E90. Plus, it even has a built-in GPS and location-based functions. But if you need to do work, the E90 allows users to open and edit office documents and runs on Symbian OS v9.2 so you can expect a level of application sophistication close to a notebook PC.
