Re: Typical views from those want to buy but don't like the price.
Wireless is wonderful except when, for example, the OH's iphone starts BSODing due to update taking most of the internal memory, and then fails on update, causing a boot loop and you have to try downloading the update to the mac, then running the update from itunes.
Which incidentally didn't work and in the end I had to plug it into a Linux box, hack the thing, then re-run the update from itunes on the mac.
Or backing the thing up prior to running updates, because Apple beta testing it's software on users never causes issues that will require rebuilding the bloody thing from scratch. I'm not sure how long it would take to back up a 128gb iphone wirelessly, but I'd imagine using USB3 is a bit faster.
And if you haven't backed up your iphone 6 then I'm assuming nothing or there is of any value to you.
