Thanks for feedback. These days I basically live on web apps for work and personal productivity stuff, and I am sure a ton of people out there do the same.
I cannot imagine Google/Salesforce/NetSuite (or similar) saying you cannot relay on the web app, you are better off installing an app in your PC.
I am conscious there will always be glitches/hiccups, and I embrace that, if I loose 5 minutes of work once or twice in 5 years it is not a big deal(even better if a bug-report can be created on the spot). If I see strange/inconsistent behaviour (a few times in one year) that cannot be investigated and I lose 25 minutes work each time, that is very scary, no idea if it is a bug, security issue etc and no apparent way to debug/trace/recover.
BTW I got a note called "Conflict <Original note title>" and later it was magically renamed "Original note title" so I ended up with 2 notes called the same, one of them is an inconsistent old version within the 25 minutes updates that strangely disappear. What worries me the most is the inability to investigate what happened and the possibility of it happening again, wondering how much of a problem this may be for other users.
