vim is a little hard to get into, but from there its benefits pay off with lots of features. On the other hand there is emacs, with an even steeper learning curve (cough long inconvenient button combos!), but it's considered so powerful, some say it's a separate operating system.
I had Comodo installed once, about 14 years ago. I had the immediate feeling that it's malware only. There is no protection, just annoying stuff that digs deep into your system, making it vulnerable.
Always use adblock, dns filter and malware scanners. Also check your privacy settings regularly and inspect network traffic to your "Smart Brain" (I just invented the term).
I imagine scenarios where you can't get rid of annoying advertisements everywhere, even in your dreams. Or people being remote controlled. Or their bank accounts emptied.
I use US ANSI keyboards from time to time. Enter key and the keys behind it used to be quite some deal before I started adapting to it. Haven't heard of EURkey yet, so I went with us-international. One thing that bothered me there though: There is no uppercase ßẞ.
You can pay in Turkish Lira, which translates roughly to 6 EUR/USD for the premium plan.
