When the Razer Edge -- then known as Project Fiona -- first debuted at CES 2012, we were intrigued by the concept of a gaming tablet with built-in controllers, but concerned about how users were expected to hold and carry it. We weren't the only ones, and Razer listened to the complaints, making the Gamepad a detachable, optional accessory. Despite making it a separate purchase, as IGN points out, "the gamepad is the preferred way to use the Edge." Play a game with it, and you'll understand why, as Engadget found it "feels right in the user's hand. The quality of the hardware sells the experience, and it's a good experience." They found the design of the buttons "top-notch," while TechRadar said "all the buttons give a satisfying press and feel like the result of excellent craftsmanship." Unfortunately, while the two together can make for a killer combo, that combo is both pricey, with a Gamepad costing $250 on top of the $1000+ you'll pay for a Razer Edge, and heavy -- as TechRadar noted, "when the tablet meets gamepad the two weigh in at a little over 4 pounds. Holding it upright in front of you is tiring after just a few minutes." While the Razer Edge is an intriguing idea, it still needs some refinement, and in the meantime, you have plenty of more comfortable options, such as Android controllers like the "A HREF="http://engadget.com/products/power-a/moga/">MOGA, or a PC gaming controller like Razer's own Onza.
