you can buy docs to go or wordsmith, another great program.
hell, buy wordsmith for 30.00, get the zire. i use a zire71 and its great. the camera i use sometimes for work, for quick shots, and as a pda palmos rules.
Also, you can often get wordsmith or docs to go with the purchase of a keyboard for the palm, so if you were thinking of getting one thats a great reason right there.
wordsmith works better than pocket word...it will use advanced fonts and formatting and will preserve more of your formatting when you sync.
its a lovely program.
so yes, while a tungsten series will come with docs to go for free, its not the only source.
fear not.
