I was introduced to Red Hat years ago. Regretfully, I did not stay with it. I now have time to get back into the game. I am concerned with my security. I have Brave and Express VPN. I want to replace Microsoft. I use QuickBooks for my business. I want an OS that is loaded on my Dell laptop. I have the ability to learn, but I would like something that isn't too heavy to start. Debian looks good. Do you have any suggestions?
