Nokia unveiled last February 2009 at the Mobile Web Congress two new members of E-series smartphones – the E75 and E55.  Successor to the highly popular E71 which was released last 2008, the Nokia E75 is a GSM dual-mode business smartphone supporting WCDMA/HSDPA, EGSM, and WLAN. The device features a side slider full QWERTY keyboard for optimal email experience. Enjoy videos, music, and graphics on the 2.4″ QVGA display and Accelerometer sensor for auto-rotate. Find directions and locations with the integrated A-GPS and included maps. Take photos with a 3.2-megapixel autofocus camera and a secondary VGA for videocall.

Additional features include USB charging with simultaneous data transfer, Bluetooth 2.0 +EDR, supports 3G, equipped with Wi-Fi 802.11 b/g, A-GPS: Nokia Maps 3.0, predictive text T9 and USB 2.0 High-Speed. Supported WCDMA frequencies depend on the region where the device is available.

Similarly, the Nokia E55 a follow up to affordable smartphone E51 also features A-GPS, Nokia Maps and N-Gage support. But since it is geared for consumers who are looking for an mid-range smartphone, its best feature would have to be its compacted QWERTY keyboard which was well loved by Nokia E51 users transitioning from the standard keypads of regular mobile phones.

Both these mobile phones are said to be loaded with Nokia’s new email interface which according to Nokia give a more efficient corporate email solution.  And to make this possible, Nokia has partnered with Microsoft and Lotus Notes.  This is a feature which made the BlackBerry devices successful in conquering the corporate mobile phone users.

With Nokia E75 and E55, people will no longer need to boot up a PC to get a full desktop email experience. The enhanced email UI includes folder and HTML email support, expandable views and sorting capability by date, sender and size, as well as the most commonly used email functions just a single click away. On top of email, the device also offer improved calendar capability, as well as contacts and task management.

Taking a lot of inspiration from Nokia’s highly business mobile device, the Nokia 9300, the E75 would cater not only to smartphone users but to mobile gamers as well.  Aside from its full support for Nokia Maps and assisted GPS feature with a 3-month license for turn-by-turn navigation, the phone is also loaded with N-Gage functionality.  So, that takes care of our Nokia mobile gamer friends’ needs.  In addition, the Nokia E75 also supports Nokia’s Ovi service, particularly useful for sharing files in the cloud.

The Nokia E55 also supports 3G and comes equipped with Wi-Fi 802.11 b/g, A-GPS: Nokia Maps 3.0 and two cameras – a 3.2-megapixel main camera and an additional VGA camera for video calls. A candybar, it´s got what it takes to be a good business oriented device. The Nokia e55 features is not any different from the one on the E75 in almost anything, except for several nice novelties like battery life, T9, internal memory, included microSD card, weight and size.

Both handsets sports a music player and FM radio with RDS and both apps come dressed in the standard Symbian OS 9.3 S60 3rd edition with Feature Pack 2 attire.

Not the least, the Nokia E-Series fleet is growing stronger. To wrap it up, the Nokia E55 and E75 both rock, so E for excellence goes both ways.
