That is seriously bad functionality. I've already been annoyed at iOS's keyboard overly autocorrecting, but to change a URL I typed in explicitly really pisses me off.
If you do get the extra m, can you play around and see what happens if you delete the extra m at the end? Does it go to realtor.co? realty.com?
I don't know why, but 5 years ago the autocorrect on iOS never bothered me much, but over the past 1-2 years it's gotten much more "wrong". It's been driving me nuts.
No - this is why the video demo does it not on his devices (where previous personal history would be relevant) but on "clean" phones in Apple Store.
EDIT: even if I type "realty.com" and hit enter, I get taken to realtor.com.
I found that if I am in private browsing mode, this does not happen.
Of course the most obvious explanation of all is that someone set up a domain redirect for the sole purpose of getting a front page on HN and Reddit. This domain seems to be very poorly ranked, yet here everyone is plugging it into their browsers and telling Google and everyone else how very important it is.
On the OSX side, the 'search' pane of settings has Safar Suggestions and Quick Website Search on, has preload top hit and show favorites off, and has DDG as the search. On IOS I have DDG as the search, and have Search Engine Suggestions, Safari Suggestions, and Quick Website Search on, and Preload Top Hit off. And have Frequently Visited Sites off.
It is worth mentioning that OSX Safari offered 'realtor.com' as a 'Top Hit' suggestion below the address bar, which I could have chosen with a quick downarrow, return, but at no point did it try to fill in autocomplete for me.
I almost wonder if this is happening to the owner of realty.com because they have spent a lot of time looking at realtor.com while building a site that competes with it, and Safari now thinks this is a site they really love to go to. — EDIT. Oh no I missed the part where there are videos of this being done on demo iPhones at the Apple store. Crazy! And not good.
