I think you hit the nail on the head. I just bought an iPad Pro, so I won’t upgrade. I don’t upgrade any of my hardware annually. But I would like to see the improvements you’ve mentioned. I think that text selection is particularly problematic on the iPad. It’s not great on iPhone either, but I tried editing a Word document on my iPad, and marking text can be extremely frustrating, unless you use a mouse.
I feel as though the iPad walled garden holds advanced applications back. Or, I suppose if you draw, iPad is a great platform, but if you produce using a keyboard and mouse, it’s not as powerful a platform as a Mac, even when using a keyboard and mouse.
I’m traveling again next week, and I will bring only my iPad, along with my card reader, USB hub and SSD drive, so that I can backup my digital photos every day. It would be nice to be able to upload them to my Synology server, but I am doubtful that I will be able to move 30+ GB of files overnight.
My iPad Pro is the 11” screen, so if and when I upgrade the hardware, I want a better screen. The color reproduction on the 11” iPad Pro screen isn’t as good as I’d like. If I understood this better, I would have bought the 12.9” model instead. For day to day use, the 11” screen is perfectly fine, but for editing RAW photos in Lightroom and trying to white balance, it’s not to my personal liking. I have no idea whether an OLED screen would be better in this respect.
