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.
