I've had my fancy ipad Air 2 for 2 days now. And all I've really done on it are things I did on my ipad 3. Web browsing, groupon, etc. I feel like I should be able to do so much more with it. Does anyone have any app suggestions that really put the Air 2 to work and really demonstrate its power and awesomeness? Something you've discovered in the past week that impressed you?
