These little memory sticks are fantastic value and superb for storing heaps and heaps of information. Incredibly simple to use by sticking them straight into a USB port and off you go. I travel for work and use a variety of computers so these are great for storing all my info, saving more stuff etc etc. Although 128MB there's plenty of space for a lot of word/excel documents. However if you've got info that takes more room (photos, videos etc.) then you will need a bigger memory. I would have over 500 docs on mine though!
