usb ports

- 3.0"L X 0.5"H X 2.25"W
- adapter: 5V 2.5A 12.5W, even the 2-prong adapter is slim! It fits "sideways" into your power strip easily without taking up two outlets =) I haven't seen an adapter with this ingenious design/orientation before.

The hub can also work without the AC adapter, but I imagine it drains power from my laptop. But it's nice to have the option.

As with any small usb hub, there's a chance that you may have difficulty fitting devices that are slightly larger than average, e.g. USB IR receiver for your mouse or some USB thumb drives. It was a tight squeeze, but I managed to carefully fit my receiver for my Wireless Optical Notebook mouse (Targus PAWM10) without too much trouble. The mouse also came with an extension cable for the receiver which would circumvent the tight fit, but that's just one more thing to plug in than necessary.) It helps that the receiver swivels 90degrees.

I've read reviews of other hubs, indicating that they overheat. I haven't experienced it myself. The Kensington remains quite cool. It is possible that without the AC adapter, it may heat up. But I'll leave that for someone else to investigate.
Connection is truly plug & play. The book even warns you about the alert when conneting backward to USB1.1 device.

I often have my pda, camera, printer, and mouse conneted simultaneously. I can't say that all devices are truly running simultaneously, but for someone who does average-to-heavy computing I haven't had any problems yet. I use my IR port for my pda now, so have freed up the port for my usb drive.

It's a great buy and very elegant--a great price through amazon. It will look great among your other trendy gadgets and fits conveniently in your laptop case, pocket, etc.
