PS/2 - Still better than USB for keyboards, USB uses CPU time and it typically only supports up to 5-key rollover, PS/2 is completely CPU free and has full N-key rollover which is good for fast typers. Alot of high end gaming keyboards aswell as most mechanicals still include PS/2 connectors for this reason.

Memory card reader - Memory cards aren't just for camera's. Alot of people use memory cards as portable storage devices and not everything has a USB port on it to connect with. They also still sell really well.

Optical drives - Physical media is still higher quality for both audio and video vs digital, 95% of digital music is in a highly compressed MP3 format which causes a large portion of the audible frequency range to be lost, quality 192/24 flac/wave files are extremely hard to find and what little is available is usually just accoustic and pink floyd, not to mention it is absurdly expensive (up to $150 for an album worth of songs).

As for video, the so called HD video content provided through digital media distribution is of a far lower bitrate than Blu-ray, neither the audio nor the video quality on them is anywhere near as good as an actual Blu-ray disk.

Also alot of gamers still prefer physical media, some games are already breaking the 50GB size mark when uncompressed, i personally do not enjoy waiting a week for a game to DL, using up 1/20th of my HDD for a single game and for some people potentially using up or exceeding the monthly DL limit. Then there are issues with reliability, HDD bites it and there goes your entire media/game collection.

I agree with the PS/2 connectors, I haven't used one of those since windows 98.

Also agree with the eSata ports, never used them either or found them useful.

DVI and VGA I still use though, never had HDMI.

I wish we were able to customize our motherboards to the point where we can get rid of the useless things that we don't want or use. I have so many ports on my mobo that I know I'll never use, plus it would be cheaper if we didn't have these things.
