In tablet mode:

Razer's advertising the Edge as "the world's most powerful tablet," and it's certainly no slouch, hyperbolic statements aside. The touchscreen quickly moves from pane-to-pane in the Windows 8 UI, and we jumped between games and other apps without a hitch. The tablet without any attachments is relatively light, but it's no more comfortable to hold long-term than any other 10-inch tablet; it's unlikely you'll be very happy hanging onto that form factor for any real length of time, though it might be hard to avoid with a touch-enabled Civilization V at your fingertips. Of course, Razer's hoping you'll snag it's detachable controller accessory (sold separately for $249, or included in a bundle with the Pro for $1499), which not only makes gaming far more ergonomic, but much more flexible from a control standpoint.

That said, as a standalone tablet, the Edge is more than capable. It's a weight match for Microsoft's Surface, but bests Microsoft's hardware in both form and function (our tune may change with the Surface Pro, but it's hard to stack up Win8 RT against Razer's full Win8 experience). It's also thankfully free of bloatware, which we always appreciate.

In tablet mode w/ game controls:

The Razer Edge with its detachable gaming controller is where the device starts really showing its strengths. Is it a bit unwieldy handling a 10.1-inch tablet while holding force feedback-enabled controllers on each side? Sure is. Is it also tantalizing playing high-def PC games on a 10.1-inch high-def IPS display with solid, console-quality controls? Double yes. Alarmingly so. Razer's applied its experience creating excellent Xbox 360 controllers (see: Onza, Sabertooth) to the Edge's controller attachment and it really shows. The buttons are solid all around -- the clicky variety we've come to expect from Razer -- and the analog sticks are above the quality we've seen on various gaming-centric tablets (we're looking at you, Wikipad). Triggers and shoulder buttons out back round out the package, and feel of similar quality to the rest of the peripheral. Switching between the controller and the touchscreen is not an option here, so you'd better be ready for some gaming should you attach it.

Beyond just offering controls, however, the attachment can be fitted with an extra 40-watt hour battery (sold separately for $69), essentially doubling the life of the Edge -- not to mention helping enable the device's portability. How much time that offers gamers in the real world is the real question. We'll put the Edge's battery through its paces when the tablet launches in the coming months, but for now Razer's touting "up to eight hours in tablet mode, two to four in PC gaming mode, and up to eight hours with extended battery." It probably wouldn't hurt to keep a power cord nearby for now.

In console mode:

Razer's console dock is perhaps the most interesting device Razer's ever created. Sure, it's "just" a dock for plugging the Edge into at home, but it essentially turns a capable gaming tablet into a full-on home gaming console -- an extremely powerful home gaming console at that. It also enables four players to get in on the fun, adding three UBS 2.0 ports (in addition to the one USB 3.0 port built into both Edge models). It also adds an HDMI out -- resultantly, Razer's Edge may be the first "Steambox" specifically because of the dock. The set up begs to be used with Steam's Big Picture Mode -- something Razer is quick to point out -- and we can't help but agree.

More importantly, though, we love the idea of simply plugging in the Edge and using it like a home console, rather than awkwardly shoehorning a computer into our home media setups. Above all else, the console dock is a game changer for both existing consoles and competing gaming laptops. It cuts out all the hassle (perceived and real) of connecting a PC to the living room TV and facilitates plug-and-play PC gaming from the comfort of the futon. Short of Valve itself releasing its rumored "Steambox" hardware standard, the Razer Edge w/ console dock is the biggest step forward for Big Picture Mode since it launched in beta. It'll be sold separately for $99.

In PC mode:

The final peripheral attachment Razer showed us this week was a full keyboard attachment and cover, which essentially transforms the Razer Edge from a tablet into a laptop. The keyboard's still a prototype, and as such won't be available for the Edge's Q1 2013 launch -- we're told it'll become available at some point in Q3, and no pricing is given. While a bit limiting, it's not hard to imagine simply
