Back in 2002 or so, you had to use IE for Korean Internet banking. It just didn't work otherwise. But that was then. This is now. 10+ years is a long time to get things done.

The ZDnet author there just doesn't know what he's talking about. He's just parroting some shit he read with zero experience. In fact, he's fucking lying and probably a piece of shit shill. Here's the proof (Korea Exchange Bank):

The line that starts "MS IE(" just says that the information below is for non-IE users to read. The next line says that you can use online banking with the OSes and browsers listed. (I'm paraphrasing.) Below the OS images, it literally says: Korea Exchange Bank Supported Operating Systems Windows, MacIntosh, Linux. Similar on the right side there.
This is not new.

So, no. Buddy is just full of shit & doesn't know what he's talking about. Both the poster above & the shill at ZDnet.
Korea is a fucking amazing country, with a wildly techno-savvy population that just adores new gadgets and technologies.
Some of the coolest shit out there comes from Korea.

If you want to find out what will be popular next year, go to Korea. You'll see it on the shelves.
