Yeah, I agree - when your looking for help this is a good site - but don't let that worry you - it's a bonus there are lots of other like minded people learning as well
I bought the cf card to run my powerpoint presentations and it works great - I used to use a optican wireless mouse so I could get away from the laptop - now I use the axim and the slimline remote that comes with the cf card. The software is great because you can either view the slides, or look at the notes - while the projector continues to show the slides.
I've now got a sd card and an additional cf card both 256mg - and to date no problems.
So keep being patient and enjoy!!!
