EDIT: If you don't agree why not explain your point instead of randomly downvoting. I believe this change is overall a good thing as it means designers and developers can stop using nasty hacks to get around the delay as they have been doing. Hopefully it will also mean more developers make the effort to make their sites work on mobile instead of the half efforts that seem to be common now.
I really don't believe that most developers of "desktop sites" care about mobile or do anything to optimize for it, and therefore wouldn't care about a 350ms delay, or even be aware of it. The people who are going to foul this up, it seems to me, are the "mobile web" developers who try to make their sites act like apps instead of just presenting content in a flexible manner.
A tip: Hold down your finger on the reload circle-arrow to load the desktop version of the page.
Fuck fixed headers / footers. Fuck social. And fuck fixed social header/footer bars specifically.
Same thing happened through the development of desktop browsing though, and it's more or less gotten better (weird fixed scroll elements in nested tables isn't a thing anymore, mostly).
Enough frameworks and abstractions and hosted services will show up and it'll get better. But, it's going to be a problem (if not a growing one) for a while still. Or, convert-to-Reader mode on mobile browsers will get a ton better and people will just get used to wiping out all the uniqueness of the sites they're browsing.
And, as a browser I still want to be able to zoom in on the 70% column the site has or override the weird 10pt font they thought looked modern in order to read it.
"responsive design" does not magically eliminate this need, and I agree with the posters saying that disabling of user-scrolling should never have even been allowed in the first place.
And that's not even touching on the fact that most "responsive" sites I've seen get it horribly wrong.
Not being able to zoom in to at least 2x, is a pain... if your content doesn't overflow, then sure set the minimum zoom to 1x, and the max to 2 or 3.. but disabling it altogether is just painful to experience... and many of the "suggestions" to fix mobile scaling include disabling zoom. I'm not even that old (40), but I imagine the problem is worse for people well into their 60's.
If you're using a font-size less than 12pt, you should emphatically NOT be disabling scaling... Unfortunately many sites/apps do just that, and often don't respect the usability settings in the OS (facebook on android was particularly bad, as in too small, before I uninstalled it).
It gets even worse when designers sell those themes to non-technical people, who have no way to fix the mess the designer caused by disabling scaling/scrolling.
