Citrix
So you can get a mouse for your phone. A normal, buttons-and-a-wheel mouse.
The real reason Citrix is making this thing is because it has lots of business customers who use its software to run Windows applications on smartphones and tablets.
But those applications can be hard to use with just a touchscreen, which is why some people might just want a mouse for their iPad, a Citrix spokesperson says.
More touch-friendly business applications are slowly but surely entering the mainstream, and Microsoft itself is pushing touch as a big part of its Windows 10 strategy.
In the meanwhile, there's a mouse. For your phone. What will they think of next?
