I've very recently worked with Xamarin Forms for about 5 full-time months and it was terrible.

My main complaints are:

* It's full of bugs

* The build system is unreliable and mysteriously breaks, which generally takes a full day to fix

* Basic functionality such as merging resource dictionaries (which are stylesheets, kinda) is missing

* No graphical UI designer or preview, so every layout change requires a recompile and deploy before you can see it

* Apps feel sluggish and crash at runtime without specific error messages

* It makes VS crash all the time. I'm not a regular VS user so I'm not sure if VS:CE2015 is a POS or if Xamarin is.

Actually they've released Xamarin Forms Previewer - https://developer.xamarin.com/guides/xamarin-forms/xaml/xaml... It's still a bit buggy but does the job in most cases. Also the latest version of Xamarin is way more stable.
