See, the iPhone 4S has some distinct advantages over the 4 IMHO:
- The camera is fantastic
- Vastly improved antenna
- 1080p video recording and stabilisation
- That dramatically beefed up CPU

This was enough for me. Siri is a nice bonus but I rarely use it. I think the key is genuinely better performance, the great camera, and great reception.

The new iPad, on the other hand... yes, the screen is beautiful... but the increased battery capacity and beefed up graphics and RAM are purely to keep that experience on par with iPad 2. I'll probably wait for an A6 iPad.
