The screen is an excellent example of resistive touchscreen technology, which can be manipulated using the finger and the stylus. The quality of the images is excellent due to the high resolution. The screen holds up well under bright sunlight, which is a relief, since it has been an issue with Nokia Xpress Music handsets.
The keyboard is also excellent, although it does not slide out fully. This seems to be a ridiculous design flaw, as the lack of space has compressed the keyboard considerably forcing the keys into multi-tasking. The arrangement is certainly not conducive to quick typing, in the event that symbols are required. The keys themselves are highly responsive, although small. Unfortunately the keys are not backlit, which would have been a nice addition to the hardware.
The homescreen is a customizable area which can hold widgets, contacts and even web pages for easy access. The pre-installed widgets are minimal but more can be downloaded easily. The homescreen consists of four menus that are accessed via side-scrolling. The second tier, namely the Task Manager, contains thumbnails of all open applications. Somewhat akin to tabbed browsing, a user can immediately view any application through it.
The contacts menu is standard, with one notable exception. Usually when the contact information is stored, there are only set ways to interact with that person. It is therefore highly appreciated when Nokia includes interaction methods based upon the information that is loaded into the contact card. For example, if a contact has a Skype account, the option to Skype with the contact is presented to the user.
The accelerometer is used as an input mechanism; calls can be silenced by turning the phone face-down. Similar actions can turn off an alarm as well.
Strangely, there is no MMS support. Therefore a user would have to use either SMS or email to correspond. It is unusual for such a simple feature to be left out, and is inexplicable. The image gallery is ordinary, strongly proclaiming the device as a business, not pleasure, phone. The music player and camera are also adequate, without being extraordinary.
Connectivity on the Nokia N900 is what lifts the phone to great heights. It supports practically every technology including, but not limited to, GPRS, EDGE and 3G. It also has an expansion slot, in addition to the 32 GB internal memory.
There is an FM transmitter built into the device, which can project clear signals on a chosen frequency. Understandably this feature is dependent on the local radio scenario, but it is still an interesting feature nonetheless.
