It’s always that one thing (or a very few).
For example, there are the several reasons why I decided to go all-in with Ulysses app for my writing despite the hefty subscription. One is because it synchronizes across iPad, iPhone and Mac seamlessly with iCloud. The next competitor which has even more features (not necessarily a plus for me) requires Dropbox and I’m not ever going to touch that thing again. So I’m locked out of that app—which is a one-time buy per device type—unless I want to do a Dropbox subscription or go without cross-device synchronized cloud backup (um, no).
And the Ulysses app is exclusively on iStuff, so…
Lock in, lock out, there’s always something. And of course it differs from person to person.
But I’m not gonna make that into a gripe. It is what it is. Choose your poison/bliss. It’s not like there aren’t alternatives. No solution is perfect.
