I purchased this micromax canvas tab p680
Recently.
It is good tablet for your basic need.
Speed is good look and feel is good.
As of now perfirmance os also good.
What is the lacking
One . No wifi direct
Two. Can not transfer application to sd card lolipop limitation
Three . Manufactory supplied app is not requiredeating space only
And.
The size is the tablet Con of tablett. Display 8inch 800×1280 pixels.
So the resolution is alright and for the price range also good.
