That's a fair answer that I can't dispute. But I'm very suspicious of Apple's motives since excluding Siri and turn-by-turn navigation from the iPhone 4 for no technical reason. Especially when they still sell the iPhone 4 and 3GS.

I could buy an iPhone 4 tomorrow for $99 on-contract. Then, I'm married to it for two more years when it doesn't even support the features of today. I just find that incredibly scummy and I doubt Apple store employees are very upfront about it with potential customers.
