You still have to hold it. (Good luck typing and holding at the same time.) And you have to block the screen to interact with it.
I've found that I moved most things to the iPad mini when I first got it. Dropbox + editorial (Python scripting!) + workflow and an updated IFTTT has me rarely reaching for my MacBook pro or heading to the iMac or Mac Pro.
Also Procreate (absolutely awesome app) has me sketching and painting again, now that I don't have to carve out space in my life for an easel and paint gear.
Hmm, this I guess has expanded beyond your comment and into being a bit of a reply to the no content creation mantra in a comment below, but there it is.
