USB hub

I need to add a USB hub to my iMac. Recommendations? Do I need a powered one like this or would this cute little Belkin do the trick?

Permanently connected devices: printer, wireless mouse receiver*, external disk drive (this is the new addition that's tipping me over the edge)
Occasional devices: iPhone, iPod, camera, jump drive

So I think the printer, disk drive, and hub would be plugged into the computer, then the wireless mouse receiver would be on the hub plus the temporaries as needed.

*It's a Logitech wireless mouse, not Bluetooth enabled. Doh.

Red sky at night....

After an unusual and stunningly red-orange sunset, we now have rain! I was hearing odd sounds out my office window, then I finally realized I was hearing raindrops splatting on the fig leaves.

It's stopped now. Wasn't even enough to connect the dots on the cement. Nonetheless, rain in August, très bizarre!
