Let the hive mind of Engadget get that for you.
"I finally got a new laptop with a lone USB 3.0 port. I'm now looking at getting a USB 3.0 hub with a power adapter so I can use both of my USB 3.0 hard drives at faster speeds. I've read lots of horror stories where some hubs either don't come with power adapters -- and as a consequence the portable drives don't work with them properly -- or they are designed poorly which results in USB 2.0 speeds. Or, the hard drives keep getting disconnected. Do your readers have any suggestions or experience using USB 3.0 hubs? Thanks!"
I don't think this is Korea's first navigation system with speech recognition. I remember a taxi driver tried to show off the speech recognition in his navigation system a couple months back, though he failed badly. I hope this thing actually works.
Also, Korea's had navigation with TV for years now. A lot of people I know have enough sense not to use it, seeing as Korea's got some of the craziest drivers I've ever seen. (A main reason I prefer public transportation here. That and gas here is $8/gallon.)
