That said, flash ram is very good for persistent storage. One very good use of an 8GB flash device would be to store an ISO-9660 image containing the static, unchanging parts of a unix-ish root filesystem. All the dynamic data (system settings, logs) could be stored on a hard drive. (Windows could benefit from this too, but it really wants all the system stuff on the C: drive. ) The main benefit would be far faster program execution; flash is a good deal faster than a hard drive, when reading. The other big advantage is that is is more impervious to unwanted changes (virii & trojans)
