I seriously doubt if anything that is answered here would help you much. If you apparently cannot think of a comprehensive list of cons and pros yourself, you apparently don't know about opportunities and bottlenecks on each platform. There are many factors to this decision, and a choice cannot be made based on a general list anyone would post here, without knowing what you want to build.
If it's going to be a desktop application, then build a desktop application. You could use a portable language (e.g. Java) to build it so you won't need to port it to several platforms.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
