5 mins? You mean less then 2 mins and I have 3 devices work just fine. Also what you called "old fashioned" is SAVER and does not need to go online to do it...
It's "safer" not saver.
Yes, I'm sorry, but for some people, saving that much time every single day, in addition to having devices synced throughout the day at all times, is worth real money. Getting it free is just a bonus. Your time isn't worth the money, and there's nothing wrong with that. Someday you may decide that it is worth it, or you may continue to think that the reduction in security, however small, is not worth it. I guess you have your Mac locked in a safe, and a security guard patrolling your house?
Gmail is not inherently insecure, if you don't click on phishing links and you have a reasonable password, you have nothing to worry about. I assume that someone as concerned with security as you are could manage to protect his Gmail account pretty well.
Where I live, the requirement to use internet to make my syncing happen is not a downside. It is for you. If your access to internet is not as reliable as some peoples', you might not agree with syncing over the internet. That's OK.
I actually use an Exchange account instead of Gmail, which offer basically the same features but slightly better performance and syncing for me. It costs me 30 cents a day. And it's worth it, so well worth it I can't even tell you. If they charged me 3 times what they do, I still would do it in an instant.
Not for you, and that's OK. Remember... it's OK if your needs are less than some others'. It's OK buddy....
