mmm, I doubt it. what app do I currently use on desktop, tablet and phone ?
a browser, that syncs automagically , and rhymes with "chrome"
a note taking app, syncs on whatever I'm on, sounds like evernote
OK, that's the list.
people are missing a huge chunk of the picture as illustrated above:
the app wars are -over-. it happened over the last few years when Microsoft was still trying to figure out how to change the office ui enough to justify another 'upgrade ' sale.
what happened? people tried/rented, and BOUGHT apps on their phone, that they wanted, while Microsoft was screaming " ours has office!"
then, when Microsoft realized people didn't want office on their phones, even for free, they had a second epiphany: people had already chosen and become content with a mobile operating system, market, and vendor.
that is why developers don't care about developing for palm, wp, sailfish, or whatever the next tiny market share following os pops up.
there simply is no incentive to Dev for the missing mimdshare
