I was way up there with you right up until I wrote the majority of my upcoming solo hip-hop record in Garageband with Audio Units on my iPad mini, with an AKAI MDP32 as my external MIDI device and an Apogee sound card for insane-quality audio.
Then, due to the amazing workflow, I was able to take those tracks into Logic Pro and refine the hell of out them. Nothing else even comes close to that workflow, as an audio producer of 14+ years.
I make skits, constantly, in iMovie, and even rough drafts of music video ideas on my Mini. Kids can do the same. It's so easy to use.
I wrote the 32-page business plan for my music label almost entirely on Pages with a bluetooth keyboard. Kids can do the same for schoolwork.
I use Pixelmator almost every day to develop high-quality images. The full photoshop is on it's way. There are no such plans for Android.[1]
Kids can even learn rudimentary code with Playgrounds. Not to mention the litany of great educational apps available.
I mean, I could see claiming an Android tablet as a 'non-producer' device, as it certainly lacks software of a quality anywhere close to GarageBand or iMovie, but the iPad?
It's like you haven't even used it, or actually have no use case to use it for creation.
