I would agree there are far better all-in-one solutions out there, but if your stuck with what you have then this works well. Having just bought the iPad, I didn't really want to take a loss and sell it right away. As far as it being awkward, I have to disagree, its so easy to use, push one button and your ready for the day, and the battery lasts a long time. Its also considered to be more accurate than the built-in GPS in most tablets, in fact many actual aircraft pilots use these for certain navigational aides in conjunction with a tablet.
I also wanted to keep the Phantom running on the Apple platform, since its nice to have the flight simulator. I've always been an Android user, so I've made the step "to the dark side" and bought my first Apple product just for the Phantom. As far as overall performance the iPad is amazing in comparison to other tablets I have tried.
