I'd argue most people would be right in not wanting to pay $0.99 for most apps. Most (the vast majority) turn out to be incomprehensibly bad, and I truly feel bad for paying for some.
IMO what we really need is a short, free (optional) trial period for many apps. You really really need to get past the "but what if it's shit?" perfectly-rational reflex when someone sees a non-free app.
