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!"
This is where I believe when we look back at history Apple will have lost their place as a dominator in the mobile space and simply be a niche player. I think Apple is great, but they don't have (at least not yet) the development infrastructure that Microsoft has as well as Google. Microsoft just makes it easy to bring out their native capabilities in your own unique application, Objective C not so much.
