MagicJackGO vs MagicJackPlus 2014

So I went to the site and noticed apparently today there is a new device called "GO" and it comes with 1 year of service. Why would they make a Plus 2014 and a GO or are these the same things re-branded?

I actually have the 1st (Desktop Only Version), 2nd (Direct Connect RJ45 to Router), and 3rd Generation (Wi-Fi Connect to Router) Dongles on hand. I remember having to buy a HP Compaq t5710 Thin Client Computer, do a Firmware Update to save OS that boots-up with the 1st Generation Dongle attached and use it without the Keyboard, Mouse, and Monitor (all 3 removed) just because it was quiet (no Fans) and used very little electricity.
