I regret investing in MonoTouch and wish I had instead just learned native iOS dev from the getgo. You need to at least be comfortable with native iOS dev to be effective with MonoTouch anyway. I have a MonoTouch written app that I can't do anything with unless I pay for a new version of MonoTouch as it's no longer compatible with current iOS releases. The constant song and dance between releases of MonoTouch and iOS updates gets frustrating after a while.

I always recommend (and when it's about employees demand) people to first learn everything native in Objective-C/Java(/C# if you need wp8 as well) before trying to unify things with C#/Xamarin, C++ or JS. That way you have a solid understanding what is possible and you don't lock yourself in. That said; Xamarin rocks and I hope MS doesn't kill it.
