I would agree with most of this. However, I'm sitting here looking at a SanDisk Extreme Pro 95MB/s 16GB SD card with a bent pin on the back which has caused it to go unreliable. I'm not without care when handling my SD cards and I've read of others having the same problem with the exposed pins on SD cards. Because of this, the closed connection and the build of CF cards seem to be more robust. For me at least, out in the field that's important.
I send data to the CF card 1st, followed by the SD card. I use a SanDisk card reader to transfer impages to my PC.
