Pros
Pro Includes an IDE
Amber includes an integrated development environment with a class browser, workspace, transcript, object inspector and debugger.
Pro Smalltalk is a simple, elegant, and powerful language
Pro One-to-one JS equivalent
Amber is written in itself, including the parser and compiler, and compiles into efficient JavaScript, mapping one-to-one with the JS equivalent.
Pro Easier transition from other paradigms
Since F# is not a purely functional language, it lends itself to being more easily picked up by programmers that have experience with other paradigms.
Pro Concise syntax
F#'s syntax tends to be terse while remaining very readable and easy to understand without being a chore to write.
Pro Runs on the CLR
Since F# runs on the Common Language Runtime or CLR, it has access to the entire .NET Framework, as well as libraries written in other .NET languages such as C#, VB.NET, and C++/CLI.
Cons
Con Very few learning resources
There are very little learning resources for Amber outside the official documentation. Which may not be enough for beginners, especially people that don't have much experience in programming.
Con Not really cross platform
Though the community sites are touting F# can be cross platform through use of Mono, the reality is that it is more of a hack to replay on larger mono applications in production.
