This is why these things are very much horses for courses, in the past three days I haven't used my iPad, other than for comparisons with the 6+.
I've been able to read everything I've looked at so far, including the macrumors desktop website. I have found only the smallest of text to be an inconvenience, but zooming in or rotating to landscape fixes that easily and to be honest I sometimes have to do that on my iPad as well so no change there then.
Naturally that will not apply to everyone and no doubt as I get older and/or my eyesight gets worse I'll be needing a magnifying glass or a 22" inch phone and the wheelbarrow that goes with it to read on. But until then I can live with the 6+.
It seems to be a progression with me, all of my 9.7" iPads up to and including the iPad Air were the perfect thing. Then it was the Retina Mini and now it's the iPhone 6+ every year they seem to be getting smaller, and with good reason.
Here's something I haven't seen mentioned so far and I don't often rock out the disability card but as it may help someone else in some way, I'll mention it now.
Four years ago an accident left me with significant nerve damage to my arm, this causes a ridiculous amount of problems and a level of pain I can't describe. Yes, to live with it I'm doped up on a cocktail of pills that would choke a horse and I literally take enough morphine to kill a bull (you build it up slowly, your body adapts, anyhoooo..) but it never takes away all of the pain... Bear with me I'm getting there, the drugs also make me waffle on
Since my accident it has become a problem to hold my iPads for any length of time, hence why they have been getting progressively smaller and lighter. And now that the 6+ has arrived it's great because yet again there is a device that is both smaller and lighter, yet has a screen just big enough to be used as an all rounder (tried several Android devices, hate the operating system.) So for me and I guess others with similar circumstances, it really is the convergence device we've been needing.
I don't think anyone could reasonably argue that even the 6+ is a perfect replacement for any iPad for every person, that's like saying a 14" television is just as good as a 55" if you sit close enough. But I do believe that it boils down to what a person can comfortably use and live with and for a lot of people the 6+ will fulfil that need.
Edit: Wow, reading that back I got bored halfway myself
