Optimus Mini in the wild

The Optimus 3-key OLED Keyboard is an interesting device. At first it started as a full blown keyboard with every key having an OLED screen which could change it's image depending on the currently working app.

Since then, it has changed (mostly because of cost) to this, a 3 key keyboard. I wish we could get the full keyboard but we'll have to make do with this.

It's nice but I wonder if it's really useful and not just a fun gizmo to play with for a while...
