- Keyboard vs touchpad
- Connectivity overload (inc 4 headphone jacks ;) vs you need a bag full of dongles
- thick and small vs thin and wide
- practically vs esthetics
I don't have high hopes of seeing it made as described but nice idea. I especially like the kvm mode. That's something I thought about long ago, it sounds like an obvious idea, easy to implement, but I've never seen it done.
If you like the look of this, the closest thing that stands a chance of actually existing is probably the upcoming GPD Micro PC. It's designed for a similar network-engineer type niche, with its ethernet jack and RS-232 port.
