Chromeos with android is a lot more useful because you have full blown desktop chrome with chrome developer tools. The new chromeos devices have convertable touch screens and basically can function as tablets. But I own the new ipad because I don't have an iphone but still want my hands on these amazing Moog ios apps for my music. Android native is terrible for music, chrome browser itself has a much more highly developed api with webmidi and webaudio than you have with native android with its java based midi library.
Most Android devices aren't capable of truly low-latency audio (sub-10ms round-trip). This makes the total addressable market for pro audio apps very small, which means device manufacturers have little incentive to spend the engineering resources to provide low latency, which makes the total addressable market for pro audio apps very small.
Unless Google start setting audio latency requirements, it's a lost cause.
It's a real shame for bedroom producers like me, I've got a disposable income but not a spare grand for an iPad pro (plus I'm an apple anti-fan :-D ).
If Google had sorted out the audio story earlier, you might still have had problems with commodity tablets, but it might have been worth somebody's while to make a tablet specifically for audio and midi. It wouldn't be a million miles away from Maschine or something like that. But I fear the opportunity's gone now, and Android tablets are just a write off.
I still have my Nexus 7 which I basically use as a Kindle.
