Documents-To-Go was bundled with my T3 and can save things in a nice, compact sub-Word format which uses hardly any memory at all. My SDCard is used for piccies and I have quite a lot (184) of Word-to-Go and excel-to-go docs in the on-board memory. It's relatively inexpensive even if you don't get it in the bundle. Saving full Word docs is still quite byte-consuming though.
