It would do them well to look into connecting their stuff into Selenium Grid like saucelabs.com. I'm currently using appdriver[1] for android and appium[2] for iOS. Both communicate with SeleniumGrid which I find nice for parallel testing and the ability to use any modern computer language since Selenium's API is generally well supported across languages.
+1 on appium support (disclaimer: I'm an appium contributor). Shouldn't be too hard for them to add since it supports real devices. Opens up the door to Selenium library support and compatibility, which would be a huge win IMO.
Oh. Hmm... well, the selenium framework is still very good. I still recommend they support it. But if their target costumers are only Microsoft stack devs then.... I have no comment.
I didn't mean it negatively, but their primary tool is a C# cross platform app builder which compiles to native code. They are a C# shop and are building products (including this new service they just bought) that make sense for their primary users. C# developers (theoretically also Linux devs running Mono).
I'd suggest throwing /yr on your pricing page for each plan. I noticed it says "Annual pricing" above the plans - But users tend to be drawn directly to the numbers; I skipped over it originally.
Are you sure the pricing is for the Testcloud or for the Xamarin development tools? I am confident that it is for the latter and the Testcloud is still in beta. Hopefully pricing released soon.

Xamarin Test Cloud is not limited to c#. Will work with Objective-C, RubyMotion, Java apps too.
