New Apple iOS 9 improves productivity
Apple's latest mobile operating system iOS 9 adds a number of nice features and one that I think is outstanding. You can now split the screen to view or work on two documents at a time. If an email mentions a date, I can slide my calendar in, check the date, maybe schedule an event and switch back to the email which is still visible. I also write a lot on my iPad (almost all of this newsletter in fact) and now I can refer to information on a website that is visible on one side of the screen while writing on the other - ditto for creating slide presentations.
Apple also played catch up with Android by installing a "back button" that is customized for the situation. If you tap in an email to open a webpage, there will be a "back to email" button at the top of the screen. There's no confusion about whether "back" means back to the previous webpage or back to another app and the button is only visible when it is needed.
