The announcements today just make me hang my head in chagrin. I love Apple products. Both my wife and I only use Macbooks, we have multiple iPads, iPods, and a second generation Apple TV. I look at this iPad Pro though and I see a totally useless device. For a device at that size, weight, and cost you would be better served buying an Macbook Air. If you want a tablet form factor then you would be better served buying…
It depends on one's use cases. I use an iPad Air for two main tasks: 1) to sketch and "paint" (using ArtRage); and 2) to make music in various apps. For these applications, screen size trumps portability (larger canvas for art, wider screen for audio timelines and more keys on keyboards). I don't think I'm going to upgrade anytime soon, but when I am looking for a newer tablet, the iPad Pro will tempt me.
I think Apple is primarily trying to attract artists and other creative types with the Pro. A good friend of mine is planning on giving up his Wacom and moving to an iPad Pro instead.
