Apple released updated sales figures. In the first three days, people ordered 10 million iPhone 6 and 6 Plus models. I guess there really was pent-up demand for an iPhone with larger screen. And that was without sales in China, which will start in the next couple of weeks.
In comparison, the Samsung Galaxy S5 sold 11 million phones in its first month of availability, back in April 2014. That was an increase of 1 million over the first month of Galaxy S4 sales. Not too shabby!
Industry observers are speculating about the way that the new iPhones will affect Android sales. My guess is that sales for phones with Android will continue to be as strong as ever. I'm looking forward to the next generation Android release (to be named Android 4.5? 5.0? "L"? lollypop? lemonade?) It's expected in October, along with a new Nexus tablet. The new OS is supposed to be faster, look better (redesigned UI), and be more power efficient.
