As you may have heard, the Apple iPhone 4 was announced at the WorldWide Developers Conference today. Let's take a look at what was termed to be as big of an upgrade as the original iPhone.
Here's a rundown of the history of changes in the past:
From the iPhone to the iPhone 3G: GPS was added, 3G Capability, slightly reduced battery life, and that's about it.
From the 3G to the 3GS: Slightly improved battery life, faster CPU, compass, 3 Megapixel camera with focus, video recording, a little more ram, an onboard graphics processor, and more storage space.
From the 3GS to the 4: 5 Megapixel camera, HD video recording (720p at 30FPS), higher density display, more battery life, front camera, rear 5 Megapixel camera with flash, improved speed, and a gyroscope.
Honestly, I think the jump from the 3G to the 3GS was bigger than the jump from 3GS to 4. Will people actually use the video chat feature? You have to be using wifi, it will only work with other iPhone 4 users, and it's VGA resolution. The improved rear camera is nice, but it's still nowhere near as good as a $50 point and shoot camera. The "HD recording" is really not HD at all. It's only 720p which is the lesser of the 2 HD standards but more importantly it is at half the frame rate of regular HD at 30 FPS instead of 60. The Apple A4 processor is a needed upgrade, but the 3GS is still pretty fast. The gyroscope– this may have the most potential, but no apps will use it in the near future and the accelerometer was already accurate enough to measure 1/4 mile times in a car with numbers comparing to $300 standalone units. If you already have an iPhone 3GS– you don't need this. If you want to shell out the $199-299 when 18 months of your contract are done, then be my guest. It's good if you want to have more multimedia capability, but think about how often you've used your iPhone camera and though "Damn, I wish this had another 2 megapixels of resolution." Maybe it's because I'm still using my original iPhone 3G, but to me, the upgrade cost is not worth the few new features, especially from an iPhone 3GS.
