Took delivery on my IPad Pro 9.7 and Pencil yesterday.
Absolutely loving it. Currently sat browsing with GAF and Sky News live in split screen over breakfast, and spent several hours yesterday glued to Football Manager Touch. Also did a bit of experimenting with the Adobe PDF reader and various other productivity apps, which all looks like it's going to serve all the purposes I feared it wouldn't just fine.
The Pencil has been a game changer for me too. I'm no artist - though I like to doodle, so I'm going to give Procreate a whirl later - but I've been using the Pencil for general navigation and especially when playing Football Manager. It's probably overkill, a bit silly and not "worth" the £99 to buy it, but it's been a really pleasant experience.
I think I'm going to be good with the 32gb model, too. The first thing I did was front load the device with every app I think I'll use for both work and entertainment, and having done that I still have 19gb left. Dat cloud doing work..
