Don't worry, there's still plenty of features that most people don't care about that techies can have mile long threads about.

  - You can't change the battery
  - It doesn't support 3D glasses and 4K cinema resolution
  - No 20MP camera with flash and replacable lens
  - There is no noticeable lag when running applications in the background, so it's actually not "true multitasking". You can't run 100 apps in the background.
  - Can't install apps without jailbreak (or dev license)
  - Doesn't have a nanoSD card
  - No USB port
