Best USB hub to match the Thunderbolt display? I just got a spanking new Apple Thunderbolt Display to work with my Macbook Air and I'm  loving it. The one thing I'm missing from my iMac is the 4 USB ports at the back (the Thunderbolt display only has 3). I realize I can use the 2 USB ports on the MBA but it's just not very convenient (plus I don't like the idea of a laptop being bogged down by earthly constraints such as a dangling phone charger cable).  

I'm looking for a USB hub with the following features:


good-looking (admittedly subjective)
can hide behind the display that I'd use to plug in the immobile equipment such as scanner, wireless dongles, etc.
Ideally, no AC power needed (but I get the feeling I won't be able to be too picky on this one).


Is there hardware out there that meets these requirements? If your answer includes a link please link to manufacturers' sites, not to sales sites, which change more frequently.
There's always the various Mac mini stackable USB hubs - those usually look pretty nice.

If you can't find a hub you like the looks of, you could always hide it:


A shelf that goes on the monitor stand to hide items behind the monitor
Or you could just tape (or velcro, thanks to @jaberg) the hub to the back of the monitor to keep it out of sight.
