Once upon a great hit in the market, the Nokia N91 has taken a little backseat off late. The handset is a little expensive as compared to its competitors and has been taken over by many other model. Yet, one things about Nokia N91 remains the same, that this handset still features some functionalities that makes it desired by the customers. Its highlights being integrated 4GB hard drive, a music player, a 2-mega pixel camera, and PIM capabilities. In terms of design, the Nokia N91 looks a little bulky and flashy. The sliver shine sure makes it eye catchy, but at 4.4 by 2.2 by 0.9 inches and 5.8 ounces, the slider phone is on the larger and heftier side.

Even if we were to gauge the slider as a music phone, our opinion would be still the same. But this solid construction also have a positive side. It enables the user to get a stronger grip of the device. The Nokia N91 features a 2.2-inch-diagonal screen that displays 262,000 colours. Below the display are two customizable soft keys, the Talk and End buttons, and a five-way navigation toggle. On closed position, the device also displays music control keys. To access the numeric keypad, the Nokia N91 needs to be slid. Though the keypad seems a little cramped. On the left spine are a volume rocker, a speaker, and a mini USB port, while on right spine are a menu shortcut key and a button to release the back cover.

The Nokia N series thrives on multimedia prowess. And while the N80 and N90 ensure photography fun, the Nokia N91 is all about music. It has a competent music player and can hold up to 3000 songs. Further , it also has the advantage of Windows Media DRM-protected files.
