Is there any data on the current distribution of Monero users by Operating system?
Useful data could include the following:
Download data from: https://getmonero.org/downloads/
Any estimates about how often each OS is used among users who build from source: https://github.com/monero-project/bitmonero
Estimates (or self reported data) on the percentage of nodes hosted by VPS (which may also answer the OS question depending on the VPS plan chosen)
Estimates (or self reported data) on the percentage of miners by OS
