I posted some of my preliminary thoughts on the iPad Pro’s software keyboard. Bottom line is that I think it’s very good. If you’re used to writing code or text with a lot of symbols, you can turn off Auto-Capitalization and Auto-Correct and make it function more or less like a regular keyboard. There’s also a video in the post that shows the speed difference with the settings on and off while typing a simple HTML document.
One worry that I have with the TextBlade is remembering all the chording combinations to input characters like angled brackets, numbers, etc. This slows me down a lot on smaller virtual keyboards (iPhones and previous generation iPads). For the coders here on the forum, do you really think you’ll be able to switch out to the TextBlade as your primary keyboard for development?
