So let’s begin the bout!

1. Size and Weight: Nexus One is thinner than Nokia N97 with 130g in weight and 11.5mm in thickness, whereas Nokia N97 weighs 150 g with a thickness of 15.9mm.

2. Display: Nexus One has a large 3.7″ Capacitive high resolution OLED display with resolution of 480×800 pixels, whereas Nokia N97 has 3.5 inches TFT resistive touch display with 360 x 640 pixels.

3. Keyboard: Nexus One has an Onscreen virtual keyboard, while Nokia N97 has Slide-out full QWERTY keyboard plus Alphanumeric Onscreen virtual keyboard (also handwriting recognition).

4. Multitouch: Nexus One has the biggest advantage with multitouch support while Nokia N97 supports multitouch only in few apps.

Every single text area in Android 2.1 is speech-to-text (Google Voice recognition) enabled, which means you can say your text messages, emails, tweets, notes to self, whatever.

5. Sensors: Nexus One has an extra mic at the back to reduce background noise, whereas Nokia N97 lacks an extra mic and thus background noise reduction features.

6. Camera: Though both phones sports a 5 megapixel camera (2592×1944 pixels) with LED flash, I believe the Nokia N97′s Carl Zeiss optic lens make it stand out.

7. Processor: The Qualcomm Snapdragon(TM) 8250 processor of the Nexus One is surely the winner, with speeds of up to 1GHz while Nokia N97′s ARM 11 processor only has 434MHz.

With audio and video playback to go with a library of 5 megapixel camera snaps, storage has become an issue. So let’s take a peak.

8. Storage: Nexus One has 512MB internal memory, 512MB RAM and expandable up to 32GB, whereas Nokia N97 has 32GB onboard, 128 MB RAM and up to 16GB expandable therefore taking this round.

9. Operating System: Nexus One runs the Google Android 2.1 os. on the other hand Nokia N97 operates on Symbian OS v9.4, Series 60 rel. 5, with Nexus One taking this round.

10. Battery: Life of removable 1400 mAh battery in Nexus One performs admirably, but I think Li-Ion 1500 mAh (BP-4L) battery on the Nokia N97 is better.

11. Video: Nexus One has the higher video resolution with 720×480  @ 20FPS, but Nokia has the fastest with 30FPS @ 640×480 pixels.

12. Trackball: Tri-color notification LED, alerts when new emails, chats, text messages arrive.

The Nexus One may have surpass the Nokia N97 smartphone in performance, display quality, and speed, but it is still not yet a full-fledged business device.

And though it may not have all the features we’d like, Nexus One greatly enhances the Google Android family with a fast processor, good call quality, and improved voice control features.

Comparing newer technology to older is a little bit unfair, ‘coz it’s pretty clear that the Nexus One is more capable than what’s found in Nokia’s N97.  But  this is by no means  just a definitive guide to what technology  we have right now compare to last 2009 and I’m pretty sure you’ll have your own opinions. You could look at a few other smaller issues but I believe these have been the most important keys.

So what had been added to the new iPhone 3GS for you not to think that it was not somewhat a low-key upgrade? Well here’s the key improvements on the iPhone 3GS that we’ve come to notice, the new iPhone 3GS has improved performance (on speed and battery life), a digital compass, bigger memory, voice control and video recording, a 3.2 megapixel autofocus camera, and the new 32GB storage option.

Improved Performance:

We’re not talking about the iPhones user interface or any additional applications – everything that runs on the iPhone 3GS can run on the iPhone 3G, but the 3GS is significantly faster “S -for speed”. Rather than to introduced new features or new apps, Apple decided to concentrate on speed over the previous generation making iPhone 3GS a ‘more powerful’ model over the previous one.

Looking at the specs, the CPU in the iPhone 3GS is clocked at 600MHz using its ARM Cortex A8, compared to 400MHz on the previous iPhone 3G. As well as this, you’ll be getting 256MB RAM compared to 128MB in the 3G. When you’re using the 3GS it feels a lot more responsive, and the speed at which applications load is staggeringly quick compared to what you’d get on the older generation.

Battery:

A surprising feature of the 3GS is increased battery life, despite a higher clock speed in the device. Battery life is always a concern in smartphones, with most lasting no more than a few hours of intensive use, but the average user will be able to get a full days charge with the new improvements to battery life.

Camera:

Beside improvements on speed and battery life is the 3.2 megapixel camera, another reason to opt for the 3GS over the 3G (2.0 MP) or other older generation. The camera in the iPhone 3GS has always been pretty shocking, although I would never use the iPhone’s camera as my main point-and-shoot, but you’ll find a 3.2 MP camera in the 3GS useful to boasts video recording and auto focusing for when taking still shots.

You’ll be surprised how much this will increase the quality of your shots over previous generations, especially when used with the new auto exposure and auto white-balance features. When it comes to the quality of your video recordings, you’ll be impressed with the quality for a mobile device, although it simply can’t compete with dedicated video recorders. Still, it’s a nice feature to have, and you can tap the screen when recording to focus your videos.

Summary:

Though the iPhone 3GS is not an insignificant step forward in the iPhone family. The Nike+ support, magnetometer (compass), video recording, voice control, better camera, better battery life and faster data network are all improvements nobody would call a step backwards.

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.

What are the benefits of 3G?
You can perform all those functions that you perform at present with your mobile devices but at much higher speed than before. It provides you with faster connectivity, faster internet access, and music entertainment with improved quality. The benefits are immense. You can avail the benefits of video calling. You can call you friend and have a video call facility. The clarity is better and the facility can be enjoyed as long as both of you are using the 3G technology.

With 3G technology it is possible to access any site on the Internet by using your phone as a modem for your computer or laptop and mail the important documents. Downloading games and songs is much faster with this technology. You can download your favorite games into your mobile and start playing. You can also download the music videos or simply the songs. The technology enable for much faster download. Hence it will take only few minutes to download movie clips or albums.

You can use your favourite search engines to find information on news headlines, get information about the evening weather so that you can plan your party. You can find out the latest baseball score and any latest news about your favorite sport. The 3G phones with their advanced feature will also enable you to watch exciting highlights of your favorite sport. With the increased speed and improved quality of the services provided in the 3G phones, you can view the multimedia data applications like movie clips and the music videos with more clear picture than with the 2.5G technology mobiles.

The 3G technology provide you with the data transmission speed of up to 2Mbps when you are using the phone on stationary mode. It also provides significantly faster data transfer rates of connectivity and increased networking and most importantly the resistance to noise.

The technology has in fact increased the bit rate thus enabling the service providers to provide high speed internet facilities, increased call volumes and host of the multimedia applications to their customers. All these services can be provided to the customers on the basis of the amount of data they transmit and not on the time for which they use the service thus making the services cheaper for us.

A great deal of potential exists for new applications in the future as 3G packet based networks will allow users to be on line all the time. The capabilities of wireless networks in terms of bandwidth must still, however, be improved upon (3GNewsroom.com, n.d.).

Conclusion:
3G is an exciting new technology that is being incorporated into mobile devices across the globe. Users are now able to make person-to-person calls, download data and do a variety of other tasks they never imagined possible all via their 3G cell phones.
