I have a rMBP 13". I also have an iPad Air 2. I'm not looking to replace the MacBook Pro at all. I don't need the iPad to be Pro. But I may want it to have a really large screen. So is the 12.9" Pro worth it as just a large iPad? That's really all I'd use it for: everything I use my 9.7" Air 2 for now + likely textbooks when I start online classes in January; I don't need or want it to be a pro device, laptop replacement, or content creation device. Does the form factor get in the way, or is it really great? Is the larger screen worth it, or too much? Is the larger 12.9" iPad worth it to get just as a traditional iPad and not a Pro? I'd appreciate any input, thanks.
