Silver I have it and I will say it's great to have. I am able to monitor CPU and Ram usage, plus there is a built in timer so when the VH goes down i can time the 15 mins before it goes up. You also have a myriad of keys off to the side that you can program for different things. They also have any custom color for the keyboard and the best part is, its back lit so you can still type and see what keys you are typing with out any exterior lights.
The G keys are programable in AH as anything you want so you have an extra 18 keyboard combination keys. One of the selling points for me is the windows lock function that they have, you can lock out the windows key so you wont get an unexpected switch to desktop. So if you want a keyboard with lots of functions I would say it is worth it. Just my 2 cents.
