Weren't most/all those things true pre-MS acquisition? OSX support in Forms is fairly recent (and awesome), but Xamarin.Mac existed well before.
I think you're agreeing with me that Xamarin is nifty. But I've been waiting for something bigger/revolutionary following the partnership. Unreasonable expectations?
Not at all. But think of it this way. If Microsoft hadn't bought Xamarin, maybe there wouldn't be so much support as it currently has. Behind covers Xamarin has improved a lot, in terms of performance for example.
