iPhone 4

I have just finished watching Steve Job's keynote speech where he introduced the iPhone 4. Even though we have seen the iPhone 4 because of the Gizmodo leak, it is still interesting because of Jobs charisma and how he presented the most important features of the new iPhone. Comparing the technical specifications of the new iPhone 4 with the latest smartphones on the market, it is roughly on par with the likes of HTC's Android and even Nokia phones. However, Apple still make it relevant because they focus on the 'why' you need this but not that, instead of focusing on 'what' is in the phone. I am not going to do a full review here as you can find many of them by Googling. Let's look at two features to illustrate my point.

Camera
- 5M pixel with LED flash. This is nothing exciting because the new Android phones come with 8M pixel camera and the upcoming Nokia N8 comes with a 12M pixel camera. 5M pixel on a small sensor is plenty in a phone form factor. If you are just viewing your photos on your phone or your computer, both of them have resolution far less than 5M pixel anyway. The front camera is not a new idea either but using it for FaceTime video calling, that's a good use of a front camera.

Display
- 'Retina display'. What a cool name! Basically Apple says that's all the resolution you will need because your eyes won't be tell the difference even if the resolution is higher. Another sensible decision with a good explanation rather than just cramming more pixels and dots per inch on the specifications.

Overall, I would say the iPhone 4 is a attractive incremental upgrade. Apple just do things a little better than everyone else and now others have to play catch up again.
