The new iPhones were introduced in September this year and after more than three months of being announced there was not even one iPhone 6 or 6 Plus to be found for sale on Friday, the day after Thanksgiving in the West coast. I was at Portland visiting friends and in the wise intention of taking advantage of the state's generous 'no sales tax' law, I wanted to buy an iPhone 6 or 6 Plus there to save some $60 odd dollars. But from Friday morning after Thanksgiving till Monday night, I found only two or three iPhone 6 phones available in the entire Portland area. Those phones were also either the 16GB or the 128GB models. It is crazy to see the demand of these iPhone 6 and 6 Plus phones be so high. The last I saw such crazy demand for the iPhone was only for the original iPhone in 2007 and that was mainly due to very low supply. So I am not surprised to see all the analysts scrambling their way to increase AAPL's price targets (via The Street) right in time for the holiday quarter's sales call. It is also important to note that there weren't any major sales discounts in lieu of Thanksgiving for Apple's iPhone 6 or 6 Plus, as usual, but virtually every unit that was available for sale was sold out!
And this is just not in the US, the iPhone 6 and 6 Plus are a huge hit globally as well (via AppleInsider).
