Several members of the F# community have combined forces to found The F# Software Foundation (FSSF) with the intention to "promote, protect, and advance the F# programming language, and to support and facilitate the growth of a diverse and international community of F# programmers". Note that Microsoft are still entirely responsible for F# on its native platform: .NET on Windows.
Although the FSSF was only just created, their website is already a gold mine of F#-related links. The "Getting F#" section refers to explanations of how to install F# on Mac, Linux, Windows, Android and iOS as well as HTML5 and GPGPU.
We fully support this movement to encourage wider adoption of F# and, in fact, we are currently experimenting with F# on the Raspberry Pi and intend to look at F# on the Google Nexus 7 tablet and the forthcoming Microsoft Surface Pro tablet.
