Input:
I use the USB reader to transfer photos from my Olympus D-400 Zoom digital camera to my iMac.  Before buying my iMac, I had used the FlashPath floppy adapter to get photos to my Mac G3 desktop machine.  This worked OK, but it was somewhat tedious to insert the flash card into the special floppy adapter, run a special application on my Mac to download the photos, quit the application, eject the floppy - and then start working with my photos.  With this USB reader, things work much more intuitively - there's no special application to deal with anymore.  The flash card simply appears as another icon on my iMac desktop, and I use the normal Finder operations to copy to/from it.
My only issue occurred in the initial setup.  My iMac was not recognizing the flash card as a legitimate device and would just keep displaying the error message "Initialize or eject?".  After a couple of emails and phone calls to customer support, I realized that I needed the "File Exchange" control panel enabled (it used to be called "PC Exchange", I believe).  The FlashPath adapter specifically probibits the enabling of that control panel.  After clearing that up, I've really enjoyed using this product.
