Sorry to insist.
Became member of this group just to be able to ask: do not underestimate the importance of the iPhone

The merit of OO is that I profit from more than a decade of continuity through different OS'ses and systems. Still use material made with ACTA and MORE many years ago, from even before my gandchildren had been born
I use it for 3 classes of things: journals, random notes and instrucion lists
One reason to stick with OO was the confidence in continuity.
To be able to making notes and journal entries on an iPhone while traveling and transfer them to the Mac is great.

You are already diversifying. This is great. But just that is an argument to protect the abiolity of always being able to provide a solid app to fall back upon.
