How many attempts does it take to plug in a USB cable? For me, it's about 3, although 1 1/2 should be the mathematical answer since it should be upside-down only half the time.
Fortunately a solution is forthcoming with the next generation's USB 3.1 cables being bi-directional, so there is no upside-down. Of course it's also faster (what new tech isn't?) and is built for the future (ditto), but fixing its most annoying feature is the best.
And wow, it only took 17 years.
