I like that it's open-source so anyone who wants to contribute or use it will be able to do so. Also that they're constantly adding new features and functionality as time goes by and their users are willing to pay them for this service. There isn't much I dislike about using pscad as far as software goes. It seems easy enough even if you've never used any form of CAD before. The only thing i have noticed while using pscad is how slow everything runs compared to what you would get at home with all those fancy graphics cards and processors. If you want something free and open source then go ahead and try out pscad. You won't regret it! We needed an affordable option to solve some fairly complex electrical design problems.
