Maybe stretching the topic but I have found good use of this as long as my USB memory outlast my own feeble shoulder mounted memory unit.:

It is a tool for personal memory saving of notes or whatever small, free, useful and portable. You still do need some sort of PC unit to read it....
I have no connection whatever to the thingy part from using it. Olov

I have some concerns about my shoulder mounted unit as well , so I'm interested to understand.

What does this thing do? How is it better than carrying your notes around in word files?

Pete,

It is in some way a little bit more organized and you can open it anywhere w/o use of a Billy G. product. Any browser will do so if you have it on a USB memory or memory card or possibly a floppy (have not tested that) you can use it where there is a connector to plug it in and a browser. And it is as software should be unless I sell it , like champagne cold, unlimited and free. Olov
