For those that are style-conscious, rest easy; this keyboard is extremely sleek and sexy. The black is mirror finish on the keyboard frame, with matte rubber keys. This makes it ideal for gaming, especially if you get sweaty fingers.
The low profile also promotes quick movement across the keyboard even if you are just touch typing and, when pressed, the keys offer a solid but subtle thud that is neither too soft and spongey or oldschool crunchy. I spend a lot of time both gaming and typing up wordy reports. The Lycosa easily makes it the most comfortable experience short of an ergonomic design. I personally don't like ergonomic layouts but others might.
The key labels are simply see-through grey, so if you have the backlight off (or even on during a bright day) it can be hard to see what key you're pressing. Chances are, if you're shelling out for a keyboard in this price range, you're probably a decent typist so this won't be a problem. The visibility issue also extends to the touch-sensitive panel where the media controls are. When the lighting is off, you'll have a bit of trouble pressing the right touch button. Added that there's no tactile feedback, you'll be learning quickly to gauge where each button out of necessity.
The extra USB 2.0 port and audio jacks are a nice touch, although most desktop speakers now have 3.5mm jacks handy too. The USB port uses it's own channel (the keyboard has two USB plugs for the computer) so it'll be full bandwidth; really great for high speed flash drives.
The driver software is easy enough to use and comes on CD with the keyboard, which is (like other Razer products) packaged in really sleek ways like Apple products. The driver software lets you assign macro keys to ANY key. The profile management also makes the gaming aspect very attractive.
All in all, a great keyboard for gamers and typists alike. Value is a bit stretching it for the features of a keyboard this price range, but if you're an enthusiast, it's definitely a logical step up from the Arctosa.
