G15 is the business!
IMO, G15 is just a cool keyboard with additional functionality, where as these gaming pads give you more function keys to use.
In your normal qwerty config, you have the following easy to reach keys;
Normal fingers = ring, middle and index:
(tab)qwert
asdf (g)
xzcv
Then numbers:
12345 (6)
(can be awkward for some)
Pinky:
shift
ctrl
caps
(z)
Thumb:
space
(b)

Now lets look at the Fang:
Normal fingers = ring, middle and index:
(tab)qwert
asdf (g)
Then numbers:
7,8,9,10,11
(tilde),1,2,3,4,5,6
(can be awkward for some)
Pinky:
alt
shift
ctrl
caps
(z)
Thumb:
space
small button
c
v
(b)
I have a merc, which is very much the same, but I find that majority of its buttons are much easier to use.
You get a lot more keys at the tip of your fingers, without having to move your hand. This is great for all kinds of games, like WoW, any fps and even RTS (Wc3 or dota).
I guess I just don't understand why the G15 is so expensive for the benefits you get. Instead, why not get a K300 Compact KBD (backlit and all) for R360 with one of these for ~R320.
