Ask HN: Browser Based or Desktop App?

Curious what HN crowds experience has been in releasing a desktop enabled version of their product?

Slack, for instance, pitches a 33% overall speed improvement, 10x benefits in some cases, etc.(a)

With those benefits one would expect that overall satisfaction would track up, leading retention and usage.

But I can't find much topical data.

I'd love to understand:

1 - What is your overall "take" rate from customers and do those cohorts behave differently?

2 - Any data that you have or studies online that make the business case?
