Streaming next-gen consoles to mobile devices is awesome – you can roam around your home playing Fallout 4 – but for some reason Microsoft hasn't given us that functionality on smartphones.
Sony's app is only compatible with a handful of high-end Xperia handsets such as the Z5 and Z5 Premium, but it's odd Microsoft hasn't introduced similar capabilities with the launch of the flagship Lumia 950 and Lumia 950 XL.
Techradar quizzed a Microsoft spokesperson during a recent London event on the lack of support for Windows 10 smartphones, and when it expects to rectify this. The short answer: there's nothing currently on the horizon.
The spokesperson told us "there are number of considerations to take into account for [smartphone] compatibility, although technically it should be possible".
You'll clearly get a very different experience on a small smartphone screen compared to a TV, laptop, monitor or even a tablet, and Microsoft shouldn't jump into mobile remote play just because Sony has.
There will be a handful of fans out there, though, who'd love to see the Xbox app extended to phones.
Plus, as smartphone screens continue to grow in size and resolution – the aforementioned Z5 Premium sports a 4K display – and the power inside them increases, getting full Xbox One access on our most treasured mobile device starts to make a lot of sense.
Let's hope Microsoft is working on it as we speak.
