What's a better word to take action| Trial or Demo

To me, the word "demo" implies limitations on the functionality of the product. "Trial" implies that I will have time-limited access to the full functionality of the product. Therefore, if I were comparing two pieces of software and one offered a "demo" and the other a "trial," I would choose the trial software.

? the words have two different meanings

Demo means you Will usually watch a demonstration of how something works
Trial usually means you can use a trial version of something usually within a time frame say 7 days

so do you want to show us how it works ? that would be a demo, or do we get to trial its use over a given time?

I've always liked trial. My favorite is a trial for x number of days without any software restrictions. Many times I've tried a "trial" but went to see if it would actually do what I wanted only to be faced with a prompt "This feature is only available in the paid for version". To me that's not a trial. I didn't get to see it work.

Also, the x number of days isn't really want I like. I like x number of uses. Many times I've downloaded a trial with a 15 day limit. I try it the first day, then plan to get back and see what it can really do. Later I go back and the software is expired and I simply remove it. I really didn't get to play with it and they lost a potential sale. Would I have purchased? Don't know, but it would be more likely if I could have actually used it.

As long as I'm on my soapbox....

Those that offer a free version with restrictions and a paid version are very smart. If someone isn't going to buy your product, you still don't want them going to the competition and buying. Why not get them hooked on your software and provide them some functionality? Eventually these people may become paying customers too. If they don't at least your competition won't get dollars because they are using your free stuff. In addition you have a "customer" and have every excuse to contact them.
