I suspect the most likely area where we might notice some advantage in speed would be when listening to audio files, particularly high quality mp3 files, or when we have very large files or large capacity CF cards with a lot of stuff on them. It's like if you have a small drawer, no matter how fast you look through it, finding things won't be tough, or take long if there's not much space to look in. If you've got a huge drawer, with large files in it, then speed might be more crucial. Will we ever need to read at 8 megs a second as some of the cards can do? No, I doubt it, and the book port doesn't even write anything that takes up that much room, so write speed is even less crucial I suspect. But at a certain point, you get what you can get. And if the less expensive card happens to be a real fast card, then get it!

It makes it hard to understand what is right when advice is inconsistant. Surely both can't be right. Either the speed of the card matters or doesn't. Cheers, Dave
