My issue is two fold; I have used my gmail address for years, and I hate having to send messages to everyone to change it. Many people don't make the change in their records when they receive the message with that change.
My second issue is that Google synchronizes across all of my platforms, tablet, smartphone, laptop, and any computer. That includes my calendar, contacts, etc. If there was a seamless way to do all of that other than Google......
My predicament exactly, plus I use AdSense for business/website search links. Like your friendly drug dealer, the first few hits are free.
You can synchronize across devices with Apple products/iCloud, including email @icloud.com, but that's leaping from the frying pan into the fire. The price we pay for convenience these days is privacy, for starters.
