Personally I now use...
- iCloud.com instead of Gmail
- DDG for search though I do have to !g like 20 to 30% of the time for things like driving directions (from X point to Y point), local movie times nearby and flights.
I still use
- YouTube
- Google Maps some as its great for getting distance between X and Y
- Google News (is there a better substitute)
- Google Photos (is there anything that compares)
Hoping in time to rely a ton less on Google products.
