The Lumia 900 is a great smartphone that will be welcomed by existing Windows Phone users. However a lack of real changes means that the device is unlikely to entice iOS and Android users to move platforms.

The Lumia 900 is a reworked version of Nokia's smaller Lumia 800 Windows Phone, with the only notable changes being its plus-sized 4.3in touchscreen and the additions of an improved 1830mAh battery and 1.3-megapixel front-facing camera.
Design and build
Nokia has made few changes to the unibody, angular design previously seen on the Lumia 800.
The two devices' similarities continue with their use of ports and inputs, with the 900 retaining the 800's minimalist approach, only packing micro-USB and headphone inputs. In fact, from afar you'd be forgiven for thinking the 800 and 900 are the same phone.
This isn't necessarily a bad thing, as having only been released in 2011 the Lumia design still feels fresh, being suitably different from Apple's iPhone and the legion of Android handsets on the market.
Nokia has also done a decent job of ensuring the 800's strengths transfer onto the 900, with the device still feeling sturdy and suitably high end, despite being made of polycarbonate rather than metal.
It's only when you see the two devices side by side or pick up the 900 (pictured below left) that you really become aware of just how much bigger and heavier it is than the 800 (below right), measuring in at 128x69x11.5mm and weighing 160g - this compares to the 800's 117x61x12.1mm dimensions and 142g weight.
In hand, this means that the device will feel unwieldy to users more used to smaller smartphones. However for those used to using large devices like Samsung's Galaxy S2 or Nexus, the Lumia 900 will feel comfortable and easy to use.
The larger chassis accommodates a sizeable 4.3in 800x480 Amoled display, which we were pleasantly surprised by. The 900's display is incredibly crisp and bright even when compared to other higher end handsets like the iPhone 4S. This is in part because of the use of ClearBlack technology, that helps ensure the display's colours are rich and sharp.
