14. Nokia N900
Key features: 3.5-inch WVGA screen, 600MHz Arm Cortex A8 processor, Maemo 5 OS, QWERTY keyboard, 32GB memory, and 5MP camera
Complex says: The N900 introduces a brand new homescreen experience courtesy of its Linux-based OS, which showcases a four-loop swipe panel and an attractive multitasking dashboard that pulls the most recent messages and updates from your social networks. Another key feature is the ability to customize and place bookmarks, contacts, and widgets at exact locations on the screen. Top it off with a surprisingly fast processor and impressive web browser, Nokia proves it doesn't need a popular OS to create a good handset.
