I just saw this and fell in love with it. I’m a multi screen phreak - I work off four screens from a laptop, its mainly office based however, the odd time I have to work remotely I have to go down to one monitor, which is a massive step down.

I saw these first a few years ago and did consider them for my Microsoft surface but never followed through on it.
I see they are advertised as a kick-start project very much slanted to the apple user but they are certainly not new technology.
Loads of these on amazon for around £200 upwards.
