What about giving away the first version of the application, and charging only for upgrades? This way the user has a chance to integrate the application into their life before you ask them for money. Nobody likes shareware--if you have an explicit time limit then people won't feel comfortable with making that app 'apart of them'.
I think pricing like this could work well for open source applications too. I see people now putting up donation suggestions with the download (see elementaryos for an example[0]). The problem is I am not going to pay for something that I have never used before. However, if I like the application, payment is easy, and the pricing is reasonable, the warm and fuzzy feeling of helping a community project that is apart of my workflow would probably be worth the money.
