In world of crowded models of phones, ASUS stands out because it does not have a confusing series of models for you. And I chose Nexus 7 purely on basis of performance.
Touch screen seems delicate but is scratch proof, ask for one and you get it for rs. 700 extra. But best thing is operatability even with the slightest touch of finger or fingernails you can run it like a pc. Good system memory to back up even my office data.
OS is android pretty smooth but I am scared of the body not sure when it would crack up. But all in all this at 17 K is worth the money shelled out.
