The N900 adds cellular network capability, which means you can stay connected virtually anywhere, but it still has much in common with those internet tablet models. It is designed to be used chiefly in landscape orientation, for example, except when you want to make a call, whereupon it switches automatically to portrait mode, like a smartphone.

In size, the N900 is closer to a smartphone at 110.9 x 59.8 x 18mm, although it is a little heavy for a mobile at 181g. The power button is on top of the case (when held in portrait format), along with a volume up/down key, camera shutter button and an infrared port.

The latter is not used by any built-in application, but is available for developers to find a use for, according to Nokia.
