Why aren't all USB connectors like this?

What then do you do about those PCs and other devices which are designed to sit either horizontally or vertically? Then you have motherboards that could be installed into either an old style horizontal desktop case or a tower.

You've never had to do the double flip? ;D Try to insert it. Doesn't fit. Flip it. Still doesn't work. Flip it again. Goes in first try now.

Yeah, they should have written into the standard, that USB connector has to be 3 dimensional, not 4 or five, like the ones that they place everywhere. And you cannot even filter on Digikey for the 3D ones.

Wouldn't help. Too many people ignored the specifications and skipped certification. They misused the USB logo or just omitted it entirely.

When I connect a USB cable, right as I am about to plug it in... I rotate it 180 degrees.   Successfully mates 90% of the time.   >:D  If you don't do this, it is wrong 90% of the time.

As far as connecror life goes,  all my main USB connectors on my computers have short USB3 male/female cables on them.  The connector on the end of the cable will wear out, not the one on the computer.

I've never managed to wear out a USB connector. I have broken a couple of them by snagging on a cable that was plugged into one though. If you are testing hardware devices and plug and unplug your USB devices hundreds of times each day then you might possibly wear one out before the whole computer is hopelessly obsolete but that isn't a typical use case.
