USB 3.0 Use with Linux

Has anyone tried any USB 3.o devices with any flavor or Linux? I've seen some sites stating that since 2.6.31 usb 3.0 is supported but linux.org/newsstates the following:

"The xHCI driver is already included in linux-next and since Linuxhttp://www.linux.org/news/2009/06/10/0004.html#2.6.30 has just been released, it should go into the main development tree from which Linux version 2.6.31 will emerge around late August. Users that want to have a look at the new driver can find it in the Git repository."

Just wanting to know general experiences if someone has taken the leap... I'm looking at a 2TB external WD drive and am also curious as to which vendor (sabrent, evga, etc) generally has the fewest issues with newer technology.

Thanks!
