It's not bad, my Nexus 7 has been an adequate appliance of a walled garden variety, so I don't want or expect a flexible operating system. It comes with all the apps I will ever need from it, such as book reader and browser. I do really hate the google plus nagging I experience every now and then.

...why? What LinkedIn integration does Android have?

It has Google integration to the point of being obnoxious.

you must not know android if you only ever used samsung (or google for that matter) flavours
