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've been using the betas for XBMC for MAC OS X for months now.. Its absolutely amazing, and with some fine tuning and skinning, it works to perfection, and looks really really elegant...
The best media centre app i've used so far, and the minor bugs it has aren't even noticeable, and never hinder the movie viewing experience...
By the way though, OSXBMC has now been renamed to PLEX....
