Reasons to Buy an iPhone

Critics of the iPhone has been focusing on Apple's super tight control over iPhone native apps, the exclusive binding with specific tel-cos and also some missing common features like video recording. Those are all true and fair, though I believe we would see some change when the most anticipated iPhone 2 is released.
With that said, there are some unique reasons why we should buy an iPhone.

1. The far most compelling reason for me to buy an iPhone is App Store. Just like iPods, it would be as popular (or popular at all) if there is no iTunes and iTunes Store. For consumers, they now don't need any PC/Mac sitting at home in order to installl apps. For developers, they don't have to set up a server and talk to credict card companies in order to sell their applications. It will be a App Store to me is a revolutionary way of distribution applications, and not just application on mobile devices. I believe the same idea would be ported over to the PC market some day.
2. Number two comes the iPhone SDK, or rather the powerful platform that iPhone has presented. Looking at the iPhone OS Programming Guide, no mobile platform has ever been so rich in such powerful APIs: Core Animination, OpenGL, Multi-Touch, 3-Dimensional Motion Sensors and more. I see not only the document, but also thousands of innovative applications and played-in-a-way-never-seen-before games.
   
3. Number three, it's APPLE. The the past decade, seldom have apple failed the consumers. Apple has a very narrow product range, but when they build a product, it's most likely the best in the market. With Nokia and other phone manufacturor holding machine guns and shooting in 360 different directions, Apple just shoot that one bullet, which will do all kinds of magical tricks and then hit that center spot.
