I'm a photographer, so I upload photos a lot. I had a CF/SD card reader for years and when it died I couldn't find a replacement. The ones I bought stopped being recognized as my Macs over time. I ended up just using a cable to download the images directly from my camera to my computer. I have a desktop iMac that I use for work at home and a Macbook for travel. Annoyingly, the Macbook is one of the newer models that doesn't have the typical USB port and I had to bring adapters to upload photos. I saw and bought it a few months ago and have been hooked ever since. Has an SD or CF card slot and I use both. Has two USB types so I can plug it straight into my Macbok or iMac. And it works the first time, every time.
