Thanks!
We get maybe 2-3 requests a week for Hype on Windows. My napkin math estimates of potential customers (those that don't write in or saw our FAQ, and then would go on to buy) shows this might lead to lower double-digit percent income coming from a Windows port. This roughly corresponds with our site traffic, which is 18% Windows users.
My general thought is (at this time) we’d do better to develop enticing new features to expand our user base than doing a Windows/web port.
