Seems all the SLRs use compact flash, is it a faster media type or somthing?

It was probably the most established. And since size is not at a premium in the larger-bodied SLRs (unlike the push for tinier and tinier P&S's), sticking to the CF format was an easy decision.

If the small tiny pins were on the memory card, it would be ok but this memory design isnt to good.

The place for the "male" connector is in the most protected spot, that is, in the camera. You wouldn't want those pins hanging off the card, even if there was a shroud protecting them. They'd get bent, regularly.
Unfortunately, they ocasionally do get bent in the camera. the usual reasons for this are:
- The card was inserted backward
- The card had a defective socket, causing the pin to be misdirected
- The user felt a resistance, but continued to push on it.
For sure, a design without those male pins, e.g. flat contacts on the edge of the card mating with curved spring contacts in the camera, is potentially better in this regard. The CF design has, however, proven very reliable and the risk of damage is quite low when the above scenarios are avoided. Pins that are bent can usually be straightened, once. I did it on my old Nikon 995 years ago and it is still working today.
FWIW, CF is still popular because it is a larger format; the large size makes it easier to build high-capacity cards, and also somewhat less expensive to manufacture.

IIRC, CF is just a short PCMCIA (PC card) form factor. the connectors and pinouts are the same. It makes the PCMCIA adapter just a bunch of strait through connections, so most laptops have a socket that can easily be adapted to CF cards.
Years ago, it was thought that all kinds of PCMCIA cards could be built (and there are a lot of PCMCIA cards available). IIRC, the PC Card group intended PC cards to be used in laptops and smaller devices (Replacing the PCMCIA cards, which were thought to be too large for "palmtop" computers).
I guess the camera guys thought that if you could stick a memory card in your DSLR, you could also stick in an ethernet adapter or wireless network connection and send your files to a PC. And the CF card had the largest memory for the smaller form factor (sounds like it was the world's tallest midget, to quote PT Barnum). |

I like SD cards because they click into place, and you can have shooting wars with your friends by clicking them as if you're taking them out, holding them down, and then quickly letting go, which shoots them out..
SD CARD WAR!!!! |
