Am I missing much by not being Cloud friendly?

[spadekevin]

Hello,

With most things in life I tend to be a Luddite and very reluctant for follow the crowd. I keep getting messages on my Iphone to sign up for "The Cloud".
Am I missing much by not being Cloud friendly? My major concern is establishing another account with another password and having personal info on another server. Also, as I understand, you need to be in a secure internet environment to access the Cloud. So if I am in a hotel/motel room I probably would not access my info. Liked to know other Boglehead's experience with the Cloud and whether it has improved their quality of life experience. For some context, I am retired and mostly use internet for entertainment and to research products and ideas.

Please help.

I didn't find the right solution from the internet.
