With ten fully customizable tactile keys with dynamic displays and a separate 4.05" LCD touch screen, the DeathStalker Ultimate takes everything we love from the Razer Blade and puts it right in the numpad area of your keyboard. Like the laptop, the LCD panel also features track pad and customizable gesture support for secondary mouse input.
In addition to the Switchblade features, the keyboard comes with: chiclet style key caps, tri-color led backlighting, 1000Hz ultrapollling, anti-ghosting, braided cable, five additional macro keys and a dedicated gaming mode. With a price tag of $250, the Deathstalker Ultimate is definitely one of the pricier gaming keyboards out there, but at least it isn't as expensive as the Optimus Popularis.
