The future seems limitless when you start downloading some of the well designed apps that are being released these days. I've been particularly blown away by the new dimension I've opened up by utilizing MIDI connectivity into my DAW (or better yet MX-1).
Aside from it being a super fun toy to surf the web and check emails, it can be a productive powerhouse for a wide variety of purposes. If you have room in your setup and wallet, there is hardly any need to compare to other tablets. The iPad Air 2 is the best one on the market to this date.
The iPad Air 2 has been my work horse in my studio, my cafe coffee runs but more especially in my sound design activities. I use it during my live sets running Field Scape, and various sound apps. A MUST HAVE!!!!
