... so decided to treat myself to a 128GB cellular IPP complete with pencil and smart keyboard.
I, too, absolutely love my iPad Pro for many of the same reasons you do.
I just wish the smart keyboard had an Esc key on it.
I use 'Prompt' regularly to ssh into different servers around the world and am often editing source code files, config files, etc, in vim and the absence of an Esc key means I'm constantly having to hit ^[ to emulate the key. Doable, but a pain in the arse. I'm likely going to start carrying a magic keyboard with my iPad Pro for those times that I need to do a lot of editing in vim...
But, yes, webpages, email, text conversations, slack, youtube, etc are all
fantastic on the Pro. Now, if only Facebook would get off their rears and update their app to support the Pro natively...
