Agreed. I have one Dell with normal front USB ports, but my other Dell box has the idiotic downward-angled ports that you can’t see, and which are mounted upside down.
And I seriously doubt it’s for dust protection, because the whole assembly has a big plastic lid (which, incidentally, is also badly designed, since it doesn’t open far enough to actually get completely out of the frickin’ way).
For the OP: the USB ports on my laptop (a Toshiba) are sideways. And any orientation besides right side up (USB logo on top) is annoying, because you want to be able to predict which direction the plug is going to go in, so you can do it without having to get your face back there and see the port.
