Nokia just unveiled the Nokia E7, an aluminum-clad slide-out QWERTY handset that is said to be the ultimate business smartphone. This new Symbian 3 device features a 4-inch tilting touchscreen display, Nokia ClearBlack technology for improved outdoor visibility, and an 8-megapixel camera that can capture 720p video at the back. What makes this device the best business device Nokia has ever produced is the ability to create and edit Power Point presentations on the go, work on documents, and review spreadsheets. Business users who are constantly on the go should definitely take a look at the Nokia E7. Expect it to hit stores late 2010 for around €495.
