I'm just interested in how quickly you can write on it compared to an iPad Mini.

Is it easy enough to type a few thousand words on it every day?

To write that much on an iPhone 6 is possible, but the mini would be easier I think. But, you can dictate using either, which when you get good, is the best!

I use my plus to type quite a bit and find it easy enough. I actually find it easier to use the plus to type as I find iPads awkward to hold. You can type with two hands on an iPad but that assumes you have it propped up or on a stand. If this is how you will use it then maybe the iPad is your thing. If I had only one device to choose from all of what I have I would keep my plus over the iPad or my Macbook. So it really just depends on how you use it. The plus for me really is the perfect device.

Just dictate

6+ is great for typing, if i had it before my iPad air i wouldn't have brought it.

Think of it as a mini mini iPad that you can make calls on.

Loving my 6s+

After a week, seems to be same size as 6.
