First off you may have noticed that the Logitech G15 has no scores. That is because when the testing was taking place, I kept getting errors that there was not enough power to run the device. This is because there is a single USB plug that runs the whole keyboard. I kept this in the review test because I wanted to show how much of a difference the Meka G1 adds by using a separate USB connection for the hub, separating the power requirements and giving the USB hub enough juice to run the Mushkin thumb drive. Now when it came down between the Meka G1 hub and the direct connection tests, you can plainly see the hub stands its ground. The difference between the hub and directly connected is so minimal that the slight decrease in speed will be transparent to the end user.
