Pros: Great for bulk storage of data/sound files or for data transport where speed isn't critical.
Cons: Slow access/read/write times where time is critical or patience is limited :)
The Bottom Line: Adequate for most users except the high enders who require faster speeds (hi-res photography etc) Completely adequate speed for playing lower-bitrate MP3s. Friend recommendation is contingent upon his particular needs.
sidraw1's Full Review: SanDisk (SDCFB-1000-768) (1 GB) CF Card
I have used this card in three different settings and it is better suited for some than others. So far this card has been used as an auxiliary storage to a desktop and laptop using a USB 1.1 reader/writer, I have also used it in various PDAs and also in a Canon S50 digital camera. I am pleased with it in the USB reader/writer since I usually only use it in this situation for backup and transport of data, or for loading data to my Pocket PC when I don't feel like using Active Sync.
In the camera if I am taking lower resolution pictures, it's great. You can't beat getting 2000 shots on one card! The card will far outlive the battery life for a shooting session. Is 2000 shots without downloading overkill? Yes, but the potential to be able to do it is nice. If you are taking high resolution shots (the S50 is a 5 megapixel camera) then I don't suggest a setting where you are taking rapid sequences of photos. The Ultra II finishes the write quicker allowing you to take the next picture quicker.
I find that it slows my Pocket PC down just because of the slow access and read times. I have MP3s and data (word/excel) files on the card, and it takes longer to bring up a directory listing when I start Excel or Word than it does if I pop the card out (even after the ignore_my_documents fix). If you use it solely for MP3s it's pretty good. I can carry around almost 50 of my CDs ripped at 56kbs quality on one of these cards.
I use GPS and ArcPad on my Pocket PC and some of the geographic coverages are very large, here is where I am disappointed since it takes quite a while to load my initial screen if I have a lot of the coverages selected. Be aware that the read speed is about 1.0 Mb/s, so if you have a 200mb georeferenced raster image that you are bringing into Arc, be prepared to wait a good three and a half minutes plus.
