Understood, completely. It doesn't need a cross platform application developed for it to work. Just sync the data between whoever's app you like, and the access online. For that matter, a properly coded website should give a good experience in a browser.
The short list of apps that would actually be used on both a desktop and phone/tablet are... welll... extremely short.
The people who keep saying this have no idea what they are talking about.
The concept is completely lost on them.
They have no need for cross platform apps and can't see the benefit of having such.
Suggesting a browser to access apps is very very short sighted and well, really old fashion.
And a really crappy way of doing things.
BTW, Chrome is a piece of crap. Always has been.
Edge is not much better unfortunately.
Cross platform apps such as Audible, which could allow one to go from the Phone in their car, pause it,
walk inside, say "XBox On", XBOX Start Audible,,,,, Xbox Play" and have it start from where you left off?
Oh right, that's just one analogy.
if that's as far as one can think to see the potential for what Cross Platform apps could be capable of.
no wonder we still don't have Minority Report computing yet. Lack of vision, and a populace stuck in neutral.
"Oh boy, oh boy, gotta get the new iPhone (but it's the same as the old iPhone), no, it's new, see? says it right here.
New 6iSUX."
Get the picture?
