Nokia announced the imminent arrival of two new Lumia smartphones at it's New York event today. The Lumia 920 and Lumia 820 devices integrate many of the things that Nokia and Microsoft having been working on during the last 18 months, including Windows Phone 8 operating system, wireless charging, PureView imaging technology and software to deliver some cool camera effects.

In brief, the key hardware specs of the Lumia 920 are:

- DISPLAY: A 4.5-inch display with a capacitive "Super Sensitive Touch" touchscreen interface that can be operated with/without gloves (utilising Synaptic's ClearPad Series 3 technology). The display delivers "PureMotion HD+", which Nokia claims is the best smartphone display technology around, combining greater than 720HD resolution with a very fast refresh rate. It also includes sunlight readability sensors and smart polarisers that change the colours and tones of the display to make it readable in direct sunlight.

- CAMERA: An 8.7MP CMOS sensor with Carl Zeiss optics, combined with Nokia's PureView imaging technology that first appeared in the 41MP Nokia 808 device a few months ago. The Lumia 920 takes excellent photos and HD video even in poor lighting conditions thanks to two key innovations: firstly an aperture of f/2.0 which allows an enormous amount of light to be captured and allows the use of a large silicon sensor in a thin form factor; and secondly floating lens technology that provides image stabilisation and allows the shutter to stay open longer without creating blurred images. Nokia claims that the Lumia 920 captures 5 to 10 times the amount of light that other cameraphones capture. The key to the image stabilisation feature is tiny springs that are mounted on the whole camera module, not just on the lens.

- BATTERY: The Lumia 920 is powered by a massive (for Nokia) 2000 mAh Li-Ion battery, but the main innovation here is the integration of wireless charging using the Wireless Power Consortium's "Qi" standard. This is a big boost for Qi and the WPC as Nokia brings other partners to the market too, including Virgin Atlantic and the Coffee Bean and Tea Leaf, who will have charging stations in their business lounges and coffee tables respectively. This will hopefully propel Qi forward to create a single standard, increasing compatibility and reducing fragmentation in the wireless charging landscape.

- PROCESSOR: Qualcomm's 1.5GHz Dual-core Snapdragon S4 processor, MSM8960, is at the heart of the Lumia 920. It's a low-power, high-performance processor built on the leading-edge 28nm process node, delivering a stutter-free user experience and long(er) battery life. The modem in the MSM8960 supports 5 LTE bands and 4 HSPDA bands. Qualcomm's stranglehold on the Windows ecosystem is now in its third year of exclusivity.

- MEMORY: 32GB NAND Flash. Nothing sensational here and no memory card slot despite WP8 now supporting removable memory. Also, only one memory capacity option, unlike some of Nokia's competitors who offer higher memory capacity options for an extra $100, over 90% of which is pure profit. Has Nokia missed a trick here?

The Lumia 820 has some subtle differences:

- DISPLAY: 4.3 inch AMOLED display with 480x800 resolution, compared with the Lumia 920's 4.5-inch IPS-TFT with 720x1280 resolution.

- CAMERA: Same resolution 8MP main camera, but an aperture of f/2.2, compared with 8MP f/2.0 on the Lumia 920.

- BATTERY: A smaller 1650mAh battery. Still with wireless charging, this time in an exchangeable shell!

- PROCESSOR: Same.

- MEMORY: 8GB embedded NAND FLASH plus a microSDHC card slot supporting up to 32GB external memory, compared with the Lumia 920's 32GB and no slot.

The Lumia 920 is the culmination and integration of technology that has appeared in multiple Nokia devices recently. It takes the best of the Lumia 900's large display size, with the aesthetically pleasing curved display on the Lumia 800 and the incredible camera technology on the Symbian-based 808 PureView and mixes them up with some cutting-edge new image stabilisation camera technology, 4G LTE support, NFC, wireless charging and of course Windows Phone 8 .... Not bad Nokia!
