Query: Very smart choice

I have two of these cards. One for my Canon S230, and one for my Ipaq. The high speed read/write speeds are most impressive. It allows that camera to be ready for the next picture before I have it framed. And the low power usage makes it possible to get many more pictures out of one charge with the camera. Canon says you can get about 475 shots out of a charge with the s230, I have managed to get as many as 520 shots on one charge! The cards have never failed on me. Even with the abuse of being thrown in my pack when I go mountain biking, they are always perfect!The card in my Ipaq holds a lot of files, many MP3s, and MPEG videos. I am able to play back compressed 320x240 videos from it on my Ipaq pretty well. Both cards have been very good to me!This card is a perfect blend of speed, reliability, power consumption, and price. Strongly considering buying another.
