It is our hopes to be on iPad, Android and Windows... A Truely Universal Navigational Suite. The code base is actually largely written for Microsoft platforms so it should not be that difficult.
Unfortunately, the Surface has not received much pilot attention, therefore it is behind the Android release. However, I’m pushing for a Microsoft release for 2014 from my end as it should be a fairly simple deployment. Additionally, there is little to no competition on the Microsoft Market. We'll see how it goes. Merry Christmas to you too.
