Messing around with a Raspberry Pi was what got me over the threshold of learning enough to utilize Linux primarily, and then eventually exclusively.

Obsessed? No. Persistently interested though.

I communicate Linux as an option when the circumstance are appropriate. It is often not worth getting involved in other people's tech decisions. My mother is now a satisfied Mint user, after she asked me if there was more pleasant and private way to use her computer. It has been great for me, because my providing tech support has gone to basically zero.
