I understand what you're saying. Sometimes though there's no substiture for using an application. You can read the features list and not reallg know how you might use those features without hands on experience. If I can't figure out in the first few days if I want something, it's probably too complex or not something I don't really need. Perhaps it's a waste of time but I guess I can think of plenty of other things that are equally or more of a waste yet I do those too. At least you have the trial option which you don't with many things. That's just my experience. As they say, your mileage may vary :-)
