I think the price tag is a very important aspect for handheld software. I did a poll once
asking you how much you were willing to pay for Laurens' forthcoming e-book/offline Sunrise reader. Concluding from this poll, I argue that most of mobile software priced at or above $20 is generally considered "expensive", whereas a price between $10 and $14.95 is more attractive to most buyers. Most of the software on my devices is priced within this range. For other commercial products that exceed my price range I try to find alternatives in the freeware section.
