As a software user, this means you can contribute to an open source project as well, and help to develop it into a product that reflects your direct preferences. You aren't "stuck" using open source software the way you would be stuck using an expensive word processor or database. You have the same access to open source software as its programmers have and in essence, you are your own customer! In other words, we can discover whether the software performs the way we want them to and should anyone try to do the same with commercial software, they'll be in for a big disappointment. Commercial software policy doesn't even allow for returns, let alone "borrowing" them to try them. The last advantage that shareware has over commercial software (but certainly not the least) is its applicability. Apparently, the Windows XP operating system requires components that weren't developed at the time Windows 98 was distributed and if we were to install Windows XP on this machine anyway, the new operating system would look for hardware that the computer didn't have. And that would be an instant recipe for failure. Of course when we talk about operating a computer, we envision more involvement than speaking on the phone or touching things on a screen. The above illustrations were just a couple of examples of how far computer technology has grown, and how far we've pushed "user-friendliness" to its limit. We tried to convince him that a fully functional computer is one that is personalized with specially selected hardware and software accessories - and that the computer purchased at the store doesn't come with these things. Unfortunately, all of our convincing was to our avail. Our client insisted that he should never need more than what came with his boxed product and that we were just trying "bilk" more money out of him. Almost all software accompanies a list of system requirements which dictates what a computer needs to have in order for the software to work properly. To minimize errors of this sort, always verify that your computer has the required components. A project management program that you're interested in may require a specific operating system, like Windows XP for example.
