It seems to me there are too many bad reviews about this phone. The Play is top notch in my opinion.
The layout is quite similar to the iphone in how the operating system works. It takes a little while to figure out exactly how everything works, but once you do, you'll find it very user friendly.
As for slow down or crashes, I've not experienced any of it. I've played games for 3 hours straight on my phone, to find no glitches or problems at all. The games are slowly expanding and it's now at a point where you have a pretty wide choice to choose from. You can use any old game app from the android market, but most aren't compatible with the game pad. Sony is now expanding it to the point that there are nearly 200 games adapted to work on the game pad, including titles such as Rainbow Six, Fifa and PES.
So, onto the next gripe. Battery life. Can anyone tell me what phone is able to hold out for longer than the Play when you're playing on it constantly? My two bosses have iPhone's and I can tell you that's not one of them.
If you're looking for a phone with battery life to last a week, then you're not looking for a smart phone. Smart phone's have processes upon processes happening in the background and foreground which eats battery life. Go and get yourself an app to monitor them and stop moaning!
Overall, with the games coming out, the similarity to the Playstation and the attention to detail, this phone gets 5 stars from me.
