Snark aside - no, no I'm not. Certainly no more special than anybody claiming they always need to try it 3 ways :)
I've used more than one computer where they're on the back and the wrong way up (most go with the 'trident' logo on top). I have a phone and a tablet that are the same plug but the opposite way up and it's small and recessed too.
In which case for the first time around, you didn't look (perhaps you couldn't, because, well, back side of the computer and all) and for the second+ time around, you completely forgot about the first time around.
If it was properly designed, you shouldn't have to look, and if your eyesight's not brilliant that might not help anyway. As to remembering, great if you only have one machine. Not so much when you have four at home, and use many different ones at work or college.
Which just brings us back to people taking a flattened plug horizontally to a port that's oriented vertically even if the port have a 180Â symmetry.
Without seeing the back side of the computer...
Are they vertical?

Or are they horizontal?

I guess you could think that it's always parallel to the longest side, but then what orientation does it have when there is no longest side?

I guess some people would just have to try it 4 ways around.
Note that I'm in no way saying that I think the USB plugs/sockets were a great design in terms of user-experience. At the time they were certainly better than most anything out there with multiple pins. Plugging in a PS/2 plug when you couldn't see the port, now that was torture. I certainly applaud the new design (for the most part).
Ultimately though, there's always going to be people who have trouble plugging devices in - for whatever reason. Some people have trouble just plugging headsets into their phones (judging by the plethora of scratches surrounding the headphone jacks). Thankfully for them, more and more peripherals are available in wireless form.
( Well, except for the power cables. Ever try to plug a U.S. plug in the wrong way around? Easy to do if you don't check which of the pins is the broader one. The C7P (device-end) is even worse. )
