Does Linux have an Amiga feel?

If I write a new virus today tell me how your anti-virus will protect you against it.

Nowadays, most decent AV packages have firewall and proactive features that not only look for particular viruses, but virus-like activity as well.  So, it's very possible that an existing AV package will catch a previously unknown virus before infection.
 
Of course some of the better viruses are written and tested to ensure they circumvent most major AV packages, so sometimes your particular AV will not help.

It is a bit ridiculous to compare the newest Windows with a 4 year old completely outdated version of Ubuntu.  

True.  Latest Ubuntu is probably even slower.

I use Linux as my main OS but don't feel the need to argue to other people they should switch to Linux;

Perhaps you don't, but trust me - there are plenty of Linux fanbois out there who don't understand how someone could actually run Windows and are very vocal about it.
 
As for the iFanbois, there is at least an equal number of Android-fanbois.
 
I guess the camp YOU'RE in is always the rational one.
