How long will it take to develop your desktop application? If it is just a few weeks or very few months go for it and test the market. If it doesn&#x27;t work after spending some marketing efforts move away. Indeed nobody can predict your success.<p>Again, I think it is very difficult to attack the desktop market even if you target a niche market for end users. Enteprises uses are a different story.<p>One more thing if you insist: look at the OSX desktop market too because the dynamics of the end user consumption are different from Windows.
