I have no Apple devices, either. I am not a fan of being trapped in an ecosystem. I prefer swirling chaos and open standards....
I like that I have one dive log that has in it all the data from every different dive computer I have ever owned.
Oceanic, Hollis, Shearwater, Seabear. At least 8 different computers (maybe 10?), I think, from at least 4 different brands (if I'm not forgetting any).
I am like you. I would not want to have my dive data locked up in a Garmin ecosystem when, in a few years, the next Awesome Shiny Dive Computer comes out, from a different brand, and I wanted to switch.
