There are thousands of users in major banks and financial institutions which still use IE and have NO plans on moving forward anytime soon. None.
I don't mean the users. I mean the companies. You really think the banks that LITERALLY control the world's economy are somehow going to be 'shamed' into upgrading their internet browsers? You might as well try shaming the moon into changing color.
I don't mean to sound condescending, but there's no other way to put this...the comments about browser support on this board show just how inexperienced many developers really are. We are not talking about installing Firefox or Chrome on a few PCs. We are talking about MASSIVE companies with BILLIONS (with a 'B') of dollars flowing through WORKING systems that have been tested into infinity and are the backbone of our economy. Should they upgrade? Sure. Will they? No. not until they've stretched the technology they are already running until it collapses.
This move by JQuery devs, I get it, but it's quickly pushing itself out of the realm of 'awesome' to 'annoyance', only suitable for small projects. I hope not, but that's what it looks like. Even 1.9.x deprecated some features that should have been left alone - we had to code them back in.
Which companies? Give us some names--that's why I'm proposing this list.
We always, always hear the same threadbare stories about mythical magical enterprise customers that can't/won't upgrade, and the little tail wags the dog, and the life for the rest of us is made harder.
All this for a use case which is basically hearsay and rumors.
As for inexperienced developers--I'll go and say that the experience I've had of watching bad compilers and system headers and christ only knows what else force native code to get uglier and uglier and less maintainable are what motivate me to try and discourage the same mistakes in Happy Web Land.
The web is barely twenty years old, arguably much younger--let's at least try and avoid sins we don't have to commit.
Edit: Or, you know, downvote me without explanation. That's pretty cool too.
I work at Montefiore Medical Center in The Bronx, NY. Much of what I do is building intranet web apps. About a year ago they upgraded (yes, upgraded) to IE7. We have 18,000 employees, but let's say we have 10,000 computers. Upgrading all of those computers, verifying that all of the hundreds of apps provided by dozens of vendors used in scores of departments is a huge and expensive project. Healthcare in NYC is a business that earns you a margin of - if you're lucky - 1%. It is difficult to justify the cost
Note that I'm not a decision maker - in fact, I'm not even in the IT department. Please don't try to argue this with me, as I may be totally wrong about what their decision factors even were. Personally, my life would be much easier if they would upgrade, but I can understand why they have not.
No one working at that level is going to disclose their customers and the technology agreements they have. That would be business suicide (and would ruin lives). Again, this isn't mom and pop shop level stuff.
But I will give you a clue. Go find a list of the top 10 biggest banks in the United States. It's almost all of them. Then go find the biggest credit card companies. It's most of them.
The problem is that some of these big companies outsource their IT. They don't want to upgrade from, say, IE6 because they know it's going to cost them a FORTUNE.
I know of at least 2 big blue chip companies with this problem.
In fact, I once had a requirement that the software we write have it's own independant auth mechanism and NOT be linked to Active Directory, "because it costs us thousands every time we ask to add a user or change a role".
