Not to be confused with Logitech, Logitec has released two USB hubs into the market that are specifically aimed towards ultrabooks. While there might be other applications, the presence of three USB ports and a network port make it right for ultrabooks.
The two units are called the LAN-GTJU3H3 and the LAN-TXU2H3A. Both weigh only 50 grams and measure just 80 x 60 x 20 mm.
The black version is the LAN-GTJU3H3. The uplink is handled by a USB 3.0 plug and it features three USB 3.0 ports. Users will also find a Gbit Ethernet port. The white version, the LAN-TXU2H3A, is based off of the USB 2.0. It has three USB 2.0 ports and a 10/100 Mbit Ethernet port. Both devices are powered by USB 3.0/2.0 ports.
A Japan launch is scheduled for later this month with no word on US availability yet. The Black LAN-GTJU3H3 will cost 5133¥, and the white LAN-TXU2H3A will cost 2,541¥. This translates to about $53.80 and $26.50, respectively.
So likely Logitech owns the trademark on the name in the U.S. and probably most of the world, while Logitec owns it in Japan (hence why Logitech changed their name in Japan). Sorta like how gmail is called googlemail in Germany because another company owns the trademark to gmail there. Fun, fun, fun.
Personally I'd like to see the old x-jack connector (from PCMCIA cards in the 1990s) revived for ethernet ports on ultrabooks. It's spring-loaded and pops out/in when you press it. Despite how fragile it looks, it survived several drops of my laptop onto it without breaking. And several times when I tripped over the LAN cable it ended up yanking the PCMCIA card out and dumping the laptop on the ground (Thinkpads FTW), instead of breaking the jack.
The name is pretty bad too, I hope whoever got that idea will be neutered.
