Currently, I am using quite a number of 3rd party apps in place of the stock apps on my iPhone. Mailbox over Mail. Fantastical over Calender. Evernote over notes. Clear instead of reminders In a sense, I wonder what incentive there might be to go back to using the original apps? I know Apple is investing a lot of resources into overhauling their look and possibly UI, but if it doesn't offer more usability, I probably won't go back to it. What about all of you? Would you be tempted to give the core apps one more try in IOS7?
