$1,000 seems pretty meager to me. If I can share well over 50% of my code across multiple platforms then that is code that I don't have to rewrite in another language. If that 50% takes more than 10 hours to reproduce (allocating my time at $100.00/hr) then it is well worth the expense. That doesn't even factor in the time saved in maintaining the application going forward.

Granted, if you are just building a small application that you don't plan to support multiple platforms then that price would seem steep.
