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!"
As much as we all love Google and pray for their new mobile phone, we mustn't forget that they are a company of software developers, not hardware.
Here is the problem and why I think the OS-only rumor is the most accurate/realistic:
If Google wanted to get into the hardware business , they would have to either a) start a new hardware infastructure from scratch, b) buy another hardware company and start from there, or c) commission another company to build something for them. None of these are very cost effective. So why not leave the the hardware to the hardware guys, and the software to the software guys. Wouldn't it make the most sense to design a mobile OS that works on any handsets and leave iClones to the other companies? Microsoft didn't enter the hardware business until almost 20 years after the companies conception and that was only with the xBox.
