Yeah, there was this word processor called Mellel
You can use it, but once you print, it has huge "UNREGISTERED " watermark all over the page :p
I think this kind of stuff is really fair, you get to learn and use it, take a taste of it..but you don't get the product.
I hate trials, 3-days, 10 days, and 30 days are not enough to make up your mind.
Well, 30 days is enough for simple software like dvd burners and word processors
but for bigger stuff like photoshop, it took me 6 months or more to learn the stuff.
I couldn't decide if I wanted to stick with it in a 30 day trial.
and software demo totally sucks, a game demo is good it gives you a feel for the game, but a an app demo SUCKS. Usually the software is so striped down, you can just do 1 function with it, its so limited.
