We hope you didn't lean too heavily on Google Calendar's text message alerts in order to keep your life organized. Google is warning that Calendar's SMS notifications will vanish for regular users (education, government and work are safe) after June 27th. The search firm argues that they're no longer needed in an era when smartphones give you a "richer, more reliable" heads-up. It's true that modern mobile devices render SMS a bit redundant. With that in mind, this isn't good news if you can't justify a smartphone on your budget, or prefer to keep most notifications off -- you may remain blissfully unaware of an event change until you reach a computer.
