Imagine if Microsoft had taken that approach when they built Xbox, they knew some products are a marathon not a race.
Starting to wonder if any of the decision makers there even remember what the early moments of a product can be like.
Xbox nearly died in development, as Bill Gates was none too pleased with the decision. Fries recalls Microsoft's "Valentine's Day Massacre" in which Bill Gates furiously ripped apart the development team for circumventing his original idea.
But yeah, it doesn't exactly inspire confidence either...
Edit: Photos is 2015, so just over 5 years old.
Out of those 3, I'd vote only Photos is successful. Whilst completely anecdotal, I don't know anyone that uses Duo or YTTV.
