I don't use the reset much, but it's nice to have if/when needed (say a system locks up). Why reduce features and keep the price the same? It's like a floppy, I haven't used floppies much in years and definitely not for storage like they were intended. But if you have to do any low level work I think a floppy is still the best way to go. Fdd access was much more bullet proof than hoping usb still works when things go south. Same thing with cases that eliminate all external bays entirely. No cd/dvd means no burning of cd's (music) or dvd's (movies) which both still prevail in home and auto (cd/dvd formats) entertainment. It also means instead of loading default software or drivers I'd have to download everything and not every area (mine included) has true broadband internet like dsl or cable. Overall in just the u.s. alone, most areas don't. That's very limiting. It doesn't hurt anything to include standard features and yet the newer cases will eliminate them and keep charging the same prices.
Who wants to go buy a car without power windows and locks or cruise control and pay the same price for it, just because the manufacturer decided no one uses it anymore. If a car is lacking options once available, I'm going to expect a lower sticker price and the same applies to cases.
The same applies to motherboards, they're doing away with ps/2 in favor of usb. Usb is far from superior for keyboards, it struggles to compete with ps/2's native n key rollover and when first booting a system myself and others have had much more issue getting usb peripherals to work on a newly built machine. Ps/2 never had that problem and actually helped with a newly built system using a z97 mobo. When I couldn't use the keyboard or mouse plugged into any of the usb ports upon first boot (prior to drivers being loaded) in order to navigate the bios I ended up using the legacy ps/2 port and it worked like a charm. I would have been in a bad position without the option and even if I don't use it for the next 2yrs, that port hardly takes up any space on the io panel. It's nice to have when you need it.
