It would be awesome to create somekind of quide on how to switch from the Google ecosystem to something different. Mail, browser, agenda, drive, photos etc. I would seriously pay 50 bucks per month to have something different without bullshit companies like Google behind it.
Just pay for office 365 or iCloud, either of them offer all the services you listed. And for much cheaper than $50/month.
I pay for G Suite personally, I have nothing against google except that I knew their free gmail account doesn’t have support and I wanted to be able to contact someone if I ever had a problem with my mail.
50 bucks? yeah that's about doable.
