Comodo 2.4 and 3.0 are COMPLETELY different programs. Comodo 2.4 is a firewall. Comodo 3.0 is a firewall with HIPS and is clearly the most powerful firewall out there. If you want a stand alone firewall and dont care about trying to stop malware in its tracks then I guess 2.4 is for you. If you want a firewall and have the protection of stopping malware or any other viruses in its track then 3.0 is for you. If you take the time and learn Comodo 3.0 its all very easy. The first thing I do after installing anything is click around through all the tabs and options to see what the program is about. 90% of what I know about Comodo 3.0 I learned myself by playing with certain settings and reading the help file.
All that is true, but it doesn't make the cpf 3 interface any more intuitive, or easily navigable. And even if you already know where all the features can be accessed, it's still a pain to have to open up 5 separate windows to get there...
There's no point lambasting people who say that they find the new cpf3 interface difficult to use with what an excellent product cpf3 is, that's not the point that they are trying to make.
