I got rid of my iPad Air 2 and got me a Dell Venue 11 Pro tablet with broadwell M CPU and real stylus support. Been a few months now and I haven't missed the iPad even once. The ipad is good if all you do is play games, but I don't have time for that. Also, its nice to plug in my tablet to a foldable dell travel keyboard and be able to type and use an actual mouse on it. Now that I got the free Windows 10 upgrade on it, you realize what a waste of money the ipad was.
What Apple needs to do is have true stylus support for notetaking and be able to plug it in a real keyboard and use a real mouse. Also they need to add file manager support like in windows. Right now its not much more than a big iPhone and since I already got an iPhone 6+, the ipad kinda becomes worthless to me.
