Yota Devices isn't well known, but the company is already making a few small ripples with original, even unusual, designs for mobile devices. Take the Yota Ruby hot spot, which I got my hands on at CTIA. LED lights glow different colors to indicate your data speed.
The Ruby's e-ink display shows you a battery meter, how many devices are connected, and if you're sharing as a public network. Sliding the switch the other direction keeps it a private network only.
