I've been thinking about the iPad Pro (eeeeerm, kind'a non stop!) and I'm still in love with it.
Especially since iOS 9, and how I have come to realise how well it will run on the Pro.
4 gigs of RAM, lovely large screen, zippy CPU/GPU power, plenty of storage ... for someone that's not going to be using the device in a "pro" capacity, and coming from an iPad 4, this is going to be a great experience.
I just love my iPad, and my iMac is hardly ever used these days.
My iPad is my radio (I just love TuneIn Pro), my web browser, my email client, my YouTube browser (Tubex is the best, in my opinion), my Twitch viewer ... it's such a huge part of my life (not wanting to sound dramatic!).
I'm not focusing on "what's missing" ... I'm just excited for what's not.
