Wacom Bamboo Capture pen tablet

Wacom Bamboo Capture pen tablet

What it is: A pressure-sensitive pen tablet and multitouch trackpad in a single package.

Why it's great: A pen tablet makes digital drawing and painting in applications like Photoshop look and feel like the real thing. The Bamboo Capture supports 1024 levels of pressure sensitivity, which translates into thicker, more opaque strokes with the force of your pen pressure. But the greatest thing about the Bamboo Capture is its touch-sensitivity, which allows it to double as a gesture-enabled touchpad for your PC or Mac. And because the pen and touch systems use different technologies, palm rejection works flawlessly when you use the pen.

Razer Mamba 2012 gaming mouse

Razer Mamba 2012 gaming mouse

You can even dial accuracy up or down—on the fly—to suit your needs. The Mamba's built-in rechargeable battery is good for 16 hours of nonstop gaming, but should you run out of juice during a three-day binge, you can plug in the mouse with its bundled cable. Oh, and the Mamba looks like an aggressive mash-up of Batman's Tumbler car from The Dark Knight and the neontastic Batmobile from 1997's Batman and Robin.

Sennheiser HD280 Pro headphones

What it is: A set of studio-quality around-the-ear headphones.

Why it's great: Though a certain doctor—Dr. Dre—may seem to have a virtual monopoly on premium headphones, Sennheiser has been building audio equipment since 1945, and is known for the high quality of its headphones, not for its rapping prowess. The HD280 Pros may not offer the visual panache of Beats, but they provide studio-caliber sound at a fraction of the Dre's price. Just what the doctor ordered.
