if everything goes that way so very soon we will not need computers at all. we would only need our mobile phones and they would let us do everything we want without any measurements. Anyhow, Android apps + native email make the PB a must buy for everyone. You should wait until those functionalities are launched to the masses before you buy.
There has been no word on an Android app store for Blackberries. The only thing we have been told is that the Blackberry PlayBook will have the ability to run Android applications sometime this summer. Everything else is pure speculation.
As per the Android app concern i would like to say that it might be not possible to use Android app store on Black Berry but Blackberry Playbook will do something about Android app. It might be possible to run Android app through Blackberry Playbook. This is really good thing if Blackberry will make Android app store on its Blackberry smartphone.
it is not possible because black berry never support any one because blackberry also a king
I'm sure it only coming for playbook not for smartphones but we don't know that yet so let's hope google will think about that but it would be dangerous for blackberry i'm just saying :P
