I don't mean to debate this just educate as it seems some people aren't aware of the facts.
"Most of the newer cameras (such as the Canon s100) use an internal memory buffer to store pictures before they are written to memory. This is why the s100 can take pictures at a rate of 2 per sec (that's 1600x1200) regardless of the cardsize. Assuming that you don't fill the buffer, the speed of the CompactFlash card should be irrelevant.

80MB LEXAR CF w/ JumpShot Cable 166.95
-$30 off $150
-$40 Rebate
=$96.95
Isn't the $12 worth 16mb more memory and the USB Jumpshot Cable ? "
First the I own the Canon S100, try taking three pictures in a row using the super-fine large mode(you need to be in manual mode for this btw) use the consecutive mode so it tries taking them at the spec'd 2 pictures per second. I can only take three pictures before the buffer fills up and then I have to wait at least 4 seconds for it to write enough before it can take the forth picture,than the wait again as it writes enough to have room for another picture, and then it still takes another 10 or so seconds to write the remaining two!
Also I am talking no rebate needed, not everybody want to deal with the pain in the butt rebates. The jump shot cable is a piece of crap not a selling point at all. I'll take the faster card but to each their own.
"The Kingston 64 meg CF card I bought from Buy,com is rated : Media Transfer Rate: Up to 3.5MB/sec "
That's a bull crap marketing spec, no cards are faster than 15X there are some 20X right now and they are the big 300plus megabyte cards. Notice Kingston doesn't say write speed, enough said. Also don't believe any "burst" rate specs either, its all about sustained write speed.
