I use appulous as a way to test apps before I purchase as there is no way to demo apps before you buy them (save for lite versions some developers create).
Most of the time I end up buying the apps on the App Store that I previously had cracked verisons of because I like getting regular, free updates when they come out, not having to wait for someone to crack the new version.
Take 'Tweetie' for example. I never would have spent the $2.99 on it had I not been able to 'try' it out before. I had a cracked version and I liked it so much, I went ahead and bought it. In my mind, it stimulates purchases on the App Store.
