Why such hate? Stupidity or just trolling? All of your pseudo arguments are completely false of course.
a) "you must search in depositories" - there is no such thing - it's called repository, and you don't have to search here - you can download and 'install' whatever you want
b) "choose outdated software" - well what could I say completely false - in fact you can get always get the newest soft available(made so far)
c) "good antivirus soft is not easy to find" - false again... is as easy as looking into repository (or searching on internet see a) ) newest version always available(see b) ); And it's good to say that estimately about 90% of viruses targets Windows/Mac OS/Android(this is based on Linux kernel, but security is poorly made there) so just by installing Linux distribution you got the very efficient antivirus
d) "worst OS in the world" - it's like on of the most important software in the world most of the web you visit is running on Linux based servers (not even mentioning non-pc devices, etc.)
In the next few years gaming will turn into Linux distribution(see Steam and it's intentions) and Windows will have a hard time to survive(unless they will justify they infinetly higher price than Linux distributions for personal usage).
So just plz
P.S.: no offense meant in this post
