I just received the 10.5 iPad Pro today, and it's gorgeous. When first turning it on I said " this screen is amazing"; but I couldn't help thinking to myself - hey, if it looks great on this 10.5in screen, it's got to look even better on a 12.9 iPad Pro. I recently sold my MBP to replace my iPad Pro 9.7 and 13" MBP combo with the new surface pro or iPad Pro. With the new iOS 11 changes, I can't help to think I'd be much happier video editing, photo editing and multitasking on the 12.9 in iPad Pro. I think this new iPad Pro 12.9 with 512gb SSD and iOS 11 will be able to do what my gen 1 12.9 in iPad Pro wasn't able to do. I don't think the 10.5 in iPad Pro will work as my only mobile device or a laptop replacement.
