Nokia's upcoming Lumia 900 is going head to head with Sony's newly unveiled Xperia S, which smartphone is better? Two of the most talked about phones to be shown-off at this year's CES in Las Vegas are Nokia's Lumia 900 and Sony's Xperia S, and it's easy to see why as both devices seem to have everything the modern consumer could ask for.
Engine Room
1st: Xperia S: 1.5GHz dual-core CPU
2nd: Lumia 900: 1.4GHz Single Core
Sony's first major release since dropping Ericsson sees the introduction of dual-core architecture in the form of a 1.5GHz dual-core CPU, which should chuck out more than enough power to have the Xperia S humming along nicely. On the other hand Nokia's Lumia 900 carries on the tradition set be the previous two iterations of the line, which is to fit the phones with 1.4GHz a single-core CPU with the clock speed ratcheted up to give the device the poke it needs.
Memory
1st: Xperia S: 16/32GB internal memory, 1GB RAM, No Micro SD slot
2nd: Lumia 900: 16 Internal Memory, 512RAM, No Micro SD slot
Xperia S device benefits from Adreno 220 graphics, 1GB RAM and either 16 or 32GB of on-board storage space, but there's no space for micro SD expansion in the device. While Lumia 900 offers only 512MB RAM and 16GB of storage, again, fails to offer expandable memory, so once you run out of gigabytes, you're out of luck, unless you take advantage of SkyDrive's 25GB of free cloud-based storage, that is.
Display
1st: Xperia S: 4.3-inch LED-backlit LCD screen, 720x1280, 342PPI
2nd: Lumia 900 : 4.3" AMOLED ClearBlack glass touchscreen, 480x800 pixels, 217ppi
Nokia's Lumia 900 features a 4.3-inch AMOLED touchscreen that operates at a resolution of 480x800 pixels and has a pixel density of 217ppi, which is hardly remarkable by anyone's standards. Sony's Xperia S on the other hand is much more with a 4.3-inch LED-backlit LCD screen operating at 720x1280 and with its pixel density of 342PPI, it's better than Apple's Retina Display-toting iPhone 4S. In addition the Xperia S also benefits from Sony's Mobile BRAVIA Engine, which tweaks the visuals to get even more from the screen!
The Design
Tie: Sony Xperia S: 128 x 64 x 10.6mm, 144g
Tie: Nokia Lumia 900: 127.8 x 68.5 x 11.5mm, 160g
Sony's Xperia S is a nice looking device takes the form of a translucent strip running along the bottom of the device. In addition the device has a slim chassis, touch sensitive controls and nice, symmetrical camera layout on the rear of the device.
Nokia's Lumia 900 is also easy on the eye. The phone is, like it's brothers, crafted from a single block of polycarbonate that takes the form of a more mature iteration of the Nokia N8, which itself was an aesthetically pleasing device.
The Lumia 900 features touch sensitive controls on the face of the device and the layout on the rear is uncluttered and functional. The Lumia series of devices has really seen Nokia up its game in terms of design, and we're pleased to see the Lumia 900 continue the trend.
Operating Systems
1st: Sony Xperia S: Android 2.3.4 Gingerbread
2nd: Nokia Lumia 900: Windows Phone 7.5
The Nokia Lumia 900 is a Windows Phone 7.5 device, so don't expect anything new or cutting edge from the software. It's the same functional, eminently usable platform that has been winning Microsoft a lot of new admirers of late. Version 7.5 or 'Mango' does have some solid improvements over the first release of the platform, such as threaded messaging, improved Live tiles and multitasking.
While Sony's Xperia S runs on version 2.3.4 of Google's Android Operating Systems, otherwise known as Gingerbread. Why Sony chose to repeat the mistakes made with previous Xperia's and outfit the phone with an ageing version of the operating system is anyone's guess – personally we'd have liked to see some Ice Cream Sandwich action.
Gripes aside the device runs well on the operating system. It's fast and smooth thanks to the Xperia S' cutting edge hardware and is customisable and powerful in the right hands.
Sitting atop the Gingerbread foundation is Sony's TimeScape UI, which adds widgets, social networking functionality and other visual tweaks to the package.
Both operating system's have tons of apps available too, with Microsoft's Windows Phone Marketplace offering 50,000+ and Google's Android Market rapidly catching up to iOS, offering over 400,000.

2nd: Nokia Lumia 900:8MP rear, 1MP front, 720p
The Xperia S features a 12-megapixel primary camera and the Exmor-R sensor is a tremendous asset to the device, capturing high quality images in quick-time. The device also boasts an LED flash, geo-tagging, touch focus, face & smile detection, 3D sweep panorama and image stabilisation, as well as 1080p video capture. 1.3-megapixel camera front , for all your video telephony needs, which can record in 720P.
