the sony ericson Xperia play is better because it is made by sony sony is the best

Nokia camera phones, their camera has about as great as a quality as other phones. If you want a phone just for a good camera, try a sony ericson or a blackberry or an Iphone.
Yes
I know that Sony Ericson batteries are not listed as one of the top 10 batteries. Sanyo, Duracell and Energizer make some of the best batteries. I think Sony Ericson batteries are average.
two different brand. Most of sony just for Japanese market. and Sony Ericsson is for world.
I believe they're made in Sweden or California.. because Sony Ecrisson is a Swedish corporation. Hope this helps...
They both are very nice phones. It depends on what you will use it for. For browsing the internet, the Xperia is nice, but if you will mainly use it for talking, get the Hero.
