Ok - thanks. I'm not as much concerned about writing speed as reading. I'd like to use my new iPaq 4355 to watch movies using "DVD to PocketPC". The 32x Lexar 512MB card is about $100USD higher though, so unless it's going to be a MUCH better experience, I might go with the lower-speed model.
I did find this page comparing a few SD cards on a few iPaq models, but it's far from a complete list. Anyone know of a similar, but more complete comparison?
