Some factory workers swiped the still unannounced device off the production line or something. Now Engadget's got their hands on the unit too, and have spent the last week or so scrutinising every element of the gizmo. Remember, it's still unannounced.

The site details everything from battery-life, to specifications and button feel. As a gaming site, we found this little tid-bit fairly interesting:

"Since we have little experience with the PSP Go, we asked a good friend of ours to compare his experience on our Xperia Play with his 50 to 100 hours of play time on his PSP Go. Interestingly, one of his first reactions was that the phone is less well balanced than the bottom-heavy PSP Go, and then he noted that the shoulder buttons could do with more depth, but this would obviously require a thicker body. That said, we both agree that the Xperia Play is still comfortable to hold, and also it has a better build quality than the PSP Go. We also noticed that the screen can be wiggled gently when closed (such phenomenon is commonly known as the "oreo effect" amongst Palm Pre users), but it's nothing major."

There's a video after the jump demonstrating the unit running emulated versions of Ridge Racer and Tony Hawk's Pro Skater. For more information on the device's specifications, head on over to Engadget.
