Sony Japan have released a video onto YouTube showing something called Dot Switch. It looks like an infra-red remote control type thing for household objects. Not that this is something new. Infra-red on phones disappeared years ago. It sounds like some of the future Sony devices will have infra-red. Xperia Blog mention the Sony Acro. It is rumoured that Sony will announce something on the 21st of February about this.
I would love to be able to turn the tv on or turn my stereo on using my phone. What makes this more annoying is that this could be done years ago using a Windows Mobile device. But hey it will be cool to use this technology again.
