I typed a note into a Sailfish OS Evernote application called Bluewhale (check the source if you're into code). Then I fiddled around the touch screen to find out how to save and return to the notebook view. Bluewhale let me do that and trash all the text I just had painstakingly inserted to the note. It did not save it automatically, it did not warn me or ask whether I want to save changes. Nothing. Nada. That's what I ended up with. Merde! (pardon my Latin...)
So P L E A S E - even if you're developing for the "unlike" mobile ecosystem - do not think that the laws of usability do not apply (see the note below from)! An architect cannot afford to defy the laws of physics - it will result in a collapse. Likewise, as software developers, you cannot look down upon user needs and behavior. You will find yourself on a crash course towards an iceberg of frustrated users that might just sink the whole boat.

Otherwise, I'm a happy Jolla passenger still. The device is fast, pretty and generally easy to use.
