Avia Sail Pro, Windows, and iPad

I've lost or damaged electronics aboard Speakeasy--it's a wet environment. I've now lost access to an older PowerBook and am looking for a computer for Speakeasy. Notebook computers are so cheap that I'm considering putting Avia Sail Pro software on Windows and piping the data through Avia to my iPad, which is what I have been doing with OS X and MacENC.
