I am retired after 36 years in corporate IT, cloud services and cyber security. Everything I ever did was windows based (since Win95!). I'm used to the OS. But this push to cloud and AI... IMHO is unnecessary. Not for a retiree whose whole IT world is contained to a laptop in a bedroom in a home. I'm a functional adult, perfectly capable of writing my own Emails and letters, of critically thinking through my own research, and I have enough external storage devices that keeping my **** on a "Cloud" is pointless.
I am going to keep with Thunderbird. I really like Mozilla - I use Firefox because I can install extensions that block all the **** that Edge allows. Thunderbird feels really, intrinsically basic - and it is all that I really need, but thanks for the pointer! Noted.
My technological life right now is contained to a Microsoft Surface laptop. In a past life, I actually was quite proficient with Unbutu (Linux), and that OS will be my fallback when MS decides that my current PC needs to be replaced.
