I am planning on getting a canon XTI camera soon. The only thing about it that I dont really like is that is uses CF cards instead of the more popular SD cards. I have a old Olympus c3000 that I got in 2001 which uses smartmedia cards. Last week I was looking for a replacement card but only one of out of like 10 places had one. Some had no idea what was I talking about. Do you think that CF cards are going to disappearg from the market soon, or is there still a healthy demand for them to keep it alive for a few more years?
