My first thought upon reading that Google will be discontinuing SMS calendar notifications was "wow, do people still use this feature?" Well, I'm sure some do. But I haven't used this feature in years. I have a few calendar elements that send me texts, ones that have been in my calendar for ages. Though I'd forgotten about this feature, it was powerful at one time. At one point, this was an amazingly powerful tool, allowing me to get calendar notifications while away from my computer. It was great to get a note a few minutes before my meeting with the details. I loved focusing in on whatever I was doing and not worrying about transitioning/leaving for my next meeting.
Anyway, this announcement and (non?) event punctuates an evolutionary element of tech: the move to smartphones and mobile.
