Does SD card matter?

[battletone]

I have a Canon Point and shoot camera with a regular 2gb SD card, and my sister has the same camera with a high-speed card. I can actually really tell the difference in time in between pictures, and when downloading the pictures on to my computer. Because of this, I think that it would be a good idea to put some money towards on a high-speed card, but not too much. A model like the Sandisk Ultra II is probably the way to go, the best combination of value and speed.

What do you consider "regular"? I find this almost impossible, at least in terms of picture taking on a point and shoot. You probably have a VERY old SD card that is not even considered normal at this point. Anything they sell now should be beyond adequate for anything but extremely fast fps cameras and/or video.

What camera/card/card reader are you using?
