New rumor from Asia says that iPad mini will have Retina display. You don't say! Of course it will have a retina display. I do not need a rumor to know that.
The iPad mini is a typical Apple first generation product. It is cool enough that it becomes widely popular, but lags obvious big features. That was the case with the first iPhone (only GSM, can you believe that?) and so on. The iPad mini's biggest flaw is the low resolution screen.
The iPad mini 2 will of course have a Retina display when it is released in 2013. Digitimes has a source that claims the same very obvious thing. The source also says that the new iPad 5 will be lighter.
