The Nokia Lumia 800 is the first Windows Phone handset to spring from the Microsoft / Nokia tie-up announced in February, and we've got our hands on an early sample to check it out.
The Nokia Lumia 800 shares its exterior styling with the previously substantially less hyped Nokia N9, a Meego-based smartphone, although the screen size is reduced from 3.9" (854x480 pixels) to 3.7" (800x480 pixels) to conform to the Windows Phone spec list.
The CPU, however, increases from the 1GHz ARM Cortex-A8 to the 1.4GHz MSM8255 Snapdragon/Scorpion which certainly helps add snap to the Windows Phone Mango OS.
The Nokia Lumia 800, although being the more expensive of the two Nokia Windows Phone offerings (the other being the budget Nokia Lumia 710) shares the Nokia N9's 16-bit AMOLED ClearBlack display whereas the Nokia Lumia 710 sports a 24-bit ClearBlack TFT.
This being said, even though the colour depth is theoretically deeper than in the Nokia Lumia 710, AMOLED screens are seen as better than the older TFT technology due to the more vivid colours and better contrast ratios.
Moving away from Nokia comparisons, the Lumia 800 also has to compete with the likes of the HTC Titan and HTC Radar Windows Mango phones. When we compare screen size we find the Nokia Lumia 800 feeling a little small with the HTC Radar and HTC Titan entering the fray with 3.8" and 4.7" screens respectively although all competitors are limited to the same 800x480 pixel resolution.
Obviously the iPhone has managed to be a success with a smaller screen at 3.5-inches, but the trend towards bigger displays is increasing all the time, and we have to say we're fans of those over four inches thanks to the improved internet and media experience.
This means that the pixel density on the Lumia 800 is a little sharper, but in our side by side comparisons we noted very little difference between the three, and even the Lumia 800 displaying text with a little less clarity.
When it comes to internal storage the Nokia Lumia 800 and HTC Titan are equal with 16GB of fixed internal storage, with the Nokia Lumia 710 and HTC Radar weighing in with 8GB a piece.
Based on the two manufacturer's product specs it soon becomes apparent that the Nokia Lumia 800 is intended to compete against the HTC Titan and the Nokia Lumia 710 with the HTC Radar.
When compared dimensionally with the HTC Titan (131.5mm x 70.7mm x 9.9mm and 160g) we note that the Nokia Lumia 800 (116.5mm x 61.2mm x 12.1mm and 142g) cuts a very slim profile, with a lighter yet reassuring weight.
The physical appearance of the Nokia Lumia 800 is a dream to observe and handle, with its smooth curves fitting snugly to the hand both with and without the protective case provided in the purchase packaging.
First impressions of the phone are mixed. If you're used to handling the current crop of super slim handsets doing the rounds in today's phone shops, you can't help but feel the Lumia 800 is a little on the chunky side, even compared to the iPhone 4S thanks to it being around 10% thicker.
However, that's not to say it isn't an attractive device, with its large 3.7-inch OLED screen pushed to the sides of the chassis and a cool curved polycarbonate shell gives the phone a very premium feel indeed.
Nokia has worked very hard on the unibody design here, making the battery inaccessible and using top-mounted flaps to cover the charging port and SIM slot - intriguingly, we're seeing a microSIM here, which seems to be the fashion for the next wave of smartphones.
It's a slightly odd system, and one that some will find a little bit difficult to get used to - but it does lend a certain sleekness to the design.
One area we can see getting consumers annoyed is on the back panel - as you can see the demo sample we tried was already scratched up, and the same thing has already begun happening on our review model.
The Nokia Lumia 800 is quite reasonably priced, costing nothing on as little as a £26 Orange or Vodafone contract with Carphone Warehouse compared with HTC Titan starting at £31 pm with Vodafone and £36 pm with Orange.
