I've got a couple Org2s (including at least one LZ64), as well as a fistful of DataPaks and an EPROM eraser, and it's surprising how nice they are for storing data without worrying about power failure. You'll want to keep frequently modified data like appointment books, to-do lists, program source code, etc. in main RAM or on RAMPaks, but for databases with infrequently changing data (e.g. contact lists), periodic backups, or compiled programs, the EPROMS are terrific. Only takes about 10-15 minutes to erase a DataPak. If the one you're currently using is full, copy everything to a blank one to reclaim space from deleted data and erase the one that's full to reuse it later.
