I am interested in this usb hub http://www.dlink.com/products/?pid=149 and was wondering if anybody has it and can offer their thoughts and opinions on it. I have an iMac and I'd like to connect the usb hub to make it easier to manage the cables to and from the usb connector on the iMac. Rather than having all of the cables running to the back and looking messy, I'd like to use the hub and be able to put it out of sight and just have one cable going to the iMac. Also, it allows me to more easily connect and disconnect items instead of having to reach in the back of the iMac. Instead, I can just place the hub somewhere that's easily accessible to connect and disconnect my perihperals. If anyboyd has used this hub or the 4 slot hub from d-link, have you had any problems with it such as the iMac not waking properly or not sleeping properly and anything else that you might be experiencing. Also, can anybody tell me if the hub is always on? I know that it's plugged in with a a/c adaptor but let's say you have items plugged into a few slots even though they're not on such as printers, is the hub on or does it turn "off" if no activity is detected through the plug after like 30 minutes or so? I'd hate for the hub to be on 24/7. That would seem like a total power vampire continually sucking power even when not used and needed.
