Lovin' Technology

I wrote in an earlier post, that I was looking for notebook computer memory. I finally found some online that is pretty inexpensive, and I'm hoping we'll soon be back to normal where computer speed is concerned. These let you download images and documents to these cute little sticks. Since I'm not too experienced with them, I want to make sure you can't damage them. I would hate to put all of my photo's on them, delete the photo's off of my hard drive, only to have something go wrong with my stick! Anyone else notice any problems??
