HTC Titan II

Two of the biggest smartphone-related announcements at the recently concluded Consumer Electronics Show (CES) came from Nokia and HTC, who unveiled Windows Phone 7.5 Mango-based devices - the Lumia 900 and the Titan II, respectively.

Although both devices support the lightning fast AT&T 4G LTE network, how do they stack up against the Samsung Focus S, one of the leading pre-CES Windows Phone smartphones?

Operating System: Basically, the OS is the only similarity between all three smartphones. All of them run on Windows Phone 7.5 Mango, which boasts features like dynamic Live Tile Information, Twitter and LinkedIn integration in the People hub, Facebook-events integrated calendar, threaded e-mail conversations support, visual voicemail, Outlook tasks support and much more. Other features of the OS include Shazam-like audio recognition, turn-by-turn Bing Maps navigation with voice guidance, Skydrive and Office 365 documents synchronization with PDF support, Microsoft Lync support, animated picture tiles, People/Groups gallery with Skydrive and Facebook sync, People Hub-integrated photo management, Zune SmartDJ multimedia mix support, video aspect ratio control capability while playback and more.

The Lumia 900 has dimensions of 127.8x68.5x11.5mm; unfortunately, it weighs a rather heavy 160 grams. The Focus S is the lightest of them all, tipping the scales at a mere 110.6 grams and dimensions of 126x66.8x8.5mm. The Titan II falls in between, measuring 132x69x13mm and weighing 147 grams.

Processor, RAM and Storage: While both the Samsung Focus S and Nokia's Lumia 900 are powered by a 1.4GHz Scorpion processor, the Focus S sports a slightly advanced 1.5GHz Scorpion processor. All three have a built in 512MB of RAM and 16GB internal storage capacity.

The Samsung Focus S has a primary 8 megapixel, 3264x2448 pixels, autofocus, LED flash rear-facing camera with features like Geo-tagging, image stabilization and smile detection.

Compared to these, the Nokia Lumia N900 has a standard Li-lon 1830 mAh battery with up to 300 hours of stand-by, 7 hours of talk time and 60 hours of music play.

Sensors: The Lumia 900 has a gyroscope, an accelerometer, a digital compass and an ambient light sensor. The HTC Titan II lacks the light sensor, in comparison to the Lumia. Meanwhile the Focus S has only the accelerometer, a proximity sensor and a compass.

Price: Although nothing is known about the pricing of both the Lumia 900 and the Titan II, the Focus S (Wi-Fi only) is available for $199 on a two-year contract.

External Storage: None of the smartphones have the external storage options which could be a major problem for interested customers. This an area that could also hurt the three companies in their attempt to make a name for themselves in the smartphone market.
