I will believe it,
have an interest in it,
consider it,
even bother to give it more than a cursory glance ...in effort / attention,

when it is on the shelf,
has a repo with "enough" apps that are functional and competitive with the opposition,
an os that isn't half baked,
a support network that functions.
essentially any or all of the above that isn't abandoned inside the first 2 years of it's deployment,
and a few other things that are important as well...
but I won't fill the page with a post like that...

I will however copy and paste this post for every "new fabulous shiny stone" that pops up...
negating wasted time by me.
