The good qualities in general are its low cost and basic ease to use. I think it is very cool that we can drop a file system on the RC to make autonomous ops better.
The annoying qualities are that it runs on 3.3 VDC instead of 5 VDC, and that the commands must be lower case and the file names must be upper case, etc. One catch using the SPI interface is that you have to send meaningless bytes to have it send data back to you, but that is the case with any SPI device.
Access to file data is very primitive, and I haven't had time to write some higher level code for accessing the data, but considering the simple task we have of simply reading from a file, it should work OK.
I have some more information here,
