SK Telecom is developing a Roomba-like vacuum robo-cleaner that users can control via their mobile phone.

We assume instead of pre-programming, if you need to vacuum you just dial in from anywhere to activate it.

Sounds good...

Coming soon - your mobile as a movie projector.

Korean company SK Telecom's "Nano projector" can project a 20-inch image, and is small enough to fit inside mobile phones.

Apparently it is commercially viable and mass production...
