But Kinect doesn’t always work. It’s simply not reliable or flexible enough. Often, I felt like I spent more time screaming at the Kinect to follow my commands then it would have taken to just pick up the controller. I begged, I pleaded with the device to do what I wanted in the most commanding yet humble tone I could muster, and on many occasions it indeed felt like I had the robotic butler of my dreams. Most of the time, though, it felt like my butler was a little hard of hearing.
There are two distinct ways the Kinect fails, and the first feels inexcusable. Many of the voice commands are extremely rigid, to the point where you need to memorize a list of exact phrases to be able to use them reliably. If you want to go to an app, for instance, you need to start by saying "Xbox go to." But if you want to go to Bing, that structure doesn't work. The correct command is "Xbox Bing," because Microsoft expects you to unquestionably understand and accept that "Bing" should be a verb. If "Xbox on" turns on the console, why doesn't "Xbox off" turn it off? Because "Xbox turn off" is the proper command, and you’ll need to memorize it. If you’re a Redbox Instant subscriber, get used to calling it "Redbox Instant by Verizon," because the Kinect won’t accept anything less. There are dozens more examples like these.

The bad
Case is boxy, heavy, and about as big as the original Xbox.
Many launch games don't pack much of a visual punch.
Controller still uses AA batteries and proprietary headsets.
Voice commands fail a good 10 to 20 percent of the time.
System requires incredible precision in what voice commands it will take.
Voice is cumbersome and annoying in many apps.
Most apps are nearly useless in snap mode.
The ugly
Kinect auto-login works inconsistently.
In-game recording was largely busted on my review unit.
Switching from game to game can delete unsaved data without warning.
Kinect IR remote doesn't have a learning function for unsupported hardware.
Verdict: Buy it if there are exclusives that appeal to you, not for the bells and whistles. Otherwise, save $100 and get a PS4.
