USB 3 still not ubiquitous
I've just been thinking ... after doing some hardware window-shopping
Why do you still get USB2 ports on laptops and PC's? Apparently USB3 (and from my own experience) can handle any USB2 / USB1 device. It used to have some incompatibility issues, but that's been sorted out since 2012.
But still you find PC's/Laptops/NAS/routers/etc. with mostly usb2 and one or 2 usb3's tucked in the back. Usually I'm p'ed off when the front ports are all USB2 and when I want to plug in my USB3 disc and get anywhere near decent speed I have to rubber-neck it around the back! This makes no sense cost-wise. The USB2 ports need their own controller and the USB3 needs yet another. So why do manufacturers place 2 chips onto the motherboard instead on the one which can handle it all? Can't they just axe the USB2 controller already? And if they've got some "stupid" reason for keeping it, what's the difference in the same reason as to why there's no more USB1 / 1.1 ports?
Sorry for asking it here, but google gave me next to no pertinent answers.
