Yota Ruby, a different kind of hot spot
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.
If you bounce back and forth among 4G, 3G, and even 2G, you'll know by looking at the colored lights.
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.
Two ways to charge
You can charge up the Ruby using the Micro-USB port.
Or, you can flip open the USB connector to charge as a USB device.
USB Modem mode
Plugging it into your computer also turns the Ruby into a wireless modem.
Globetrotters can swap SIM cards by country, and mutliband support means you should be able to use it almost anywhere.
