A thing that i like is that Bitfence Cyber Security software will be also run on mini computers like a raspberry pi! 
But not that many people use a raspberry pi or what you said: mini computers. I think that they should focus first on normal computers and if that goes right then expand to the mini computers etc. Yea, it will be nice if the focus will be on windows and mac operating systems as that is where the market is, others can come later, i understand that is good to give preference but as it is, windows and mac are the basic foundation of creating any successful cyber security software
