These are the only ones I can think of:

There aren't *that* many out there. I have an adapter to convert to micro (on far left side of that image) from mini (second from left in that image), and that covers me on almost every new device. I have a few standard B-type connectors (center in image) laying around somewhere, but I can't remember the last time I actually needed one.
There's a couple of different phone ones too. It's gotten crazy how proprietary cable the world has gotten. Heaven forbid you get to use one cable for more than one type/brand
And yet a curious thing has happened to me. We have three different phones: Blackberry (work), Samsung and Palm Pre and they all use the same freaking cable for charging/data!!!!!
I thought I had died and gone to heaven. Its so nice not to have to dig around and swear all the time as I find 4 cables that would work with a Samsung and not the Palm that I currently need a cable for
